ISL28136 ISL28136, ISL28236 ISL28236 ® Data Sheet June 28, 2007 5MHz, Single and Dual Precision Rail-toRail Input-Output (RRIO) Op Amps The ISL28136 ISL28136 and ISL28236 ISL28236 are low-power single and dual operational amplifiers optimized for single supply operation from 2.4V to 5.5V, allowing operation from one lithium cell or two Ni-Cd batteries. These devices feature a gain-bandwidth product of 5MHz and are unity-gain stable with a -3dB bandwidth of 13MHz. These devices feature an Input Range Enhancement Circuit (IREC) which enables them to maintain CMRR performance for input voltages greater than the positive supply. The input signal is capable of swinging 0.25V above the positive supply and to the negative supply with only a slight degradation of the CMRR performance. The output operation is rail-to-rail. The parts typically draw less than 1mA supply current per amplifier while meeting excellent DC accuracy, AC performance, noise and output drive specifications. Operation is guaranteed over -40°C to +125°C temperature range.

The parts are designed to operate from single supply (2.4V to 5.5V) or dual supply (±1.2V to ±2.75V). The parts have an input common mode range that extends 0.25V above the positive rail and down to the negative supply rail. The output operation can swing within about 3mV of the supply rails with a 100k load. Rail-to-Rail Input Many rail-to-rail input stages use two differential input pairs, a long-tail PNP (or PFET) and an NPN (or NFET). Severe penalties have to be paid for this circuit topology. As the input signal moves from one supply rail to another, the operational amplifier switches from one input pair to the other causing drastic changes in input offset voltage and an undesired change in magnitude and polarity of input offset current. The ISL28136 ISL28136 and ISL28236 ISL28236 achieve input rail-to-rail operation without sacrificing important precision specifications and degrading distortion performance. The devices' input offset voltage exhibits a smooth behavior throughout the entire common-mode input range. The input bias current versus the common-mode voltage range gives an undistorted behavior from typically down to the negative rail to 0.25V higher than the positive rail. Rail-to-Rail Output A pair of complementary Bi-polar devices are used to achieve the rail-to-rail output swing. The PNP sinks current to swing the output in the negative direction. The NPN sources current to swing the output in the positive direction. The ISL28136 ISL28136 and ISL28236 ISL28236 with a 100k load will swing to within 3mV of the positive supply rail and within 3mV of the negative supply rail. Results of Over-Driving the Output Caution should be used when over-driving the output for long periods of time. Over-driving the output can occur in two ways. 1) The input voltage times the gain of the amplifier exceeds the supply voltage by a large value or, 2) The output current required is higher than the output stage can deliver. These conditions can result in a shift in the Input Offset Voltage (VOS) as much as 1µV/hr. of exposure under these conditions. IN+ and IN- Input Protection All input terminals have internal ESD protection diodes to both positive and negative supply rails, limiting the input voltage to within one diode beyond the supply rails. They also contain back-to-back diodes across the input terminals ("Pin Descriptions" on page 10 - Circuit 1). For applications where the input differential voltage is expected to exceed 0.5V, an 11 external series resistor must be used to ensure the input currents never exceed 5mA (Figure 38). VIN VOUT RIN + RL FIGURE 38. INPUT CURRENT LIMITING Enable/Disable Feature The ISL28136 ISL28136 offers an EN pin that disables the device when pulled up to at least 2.0V. In the disabled state (output in a high impedance state), the part consumes typically 10µA at room temperature. The EN pin has an internal pull down. If left open, the EN pin will pull to the negative rail and the device will be enabled by default. The EN pin should never be left floating. When not used, the EN pin should either be left floating or connected to the V- pin. By disabling the part, multiple ISL28136 ISL28136 parts can be connected together as a MUX. In this configuration, the outputs are tied together in parallel and a channel can be selected by the EN pin. The loading effects of the feedback resistors of the disabled amplifier must be considered when multiple amplifier outputs are connected together. Note that feed through from the IN+ to IN- pins occurs on any Mux Amp disabled channel where the input differential voltage exceeds 0.5V (e.g., active channel VOUT = 1V, while disabled channel VIN = GND), so the mux implementation is best suited for small signal applications. If large signals are required, use series IN+ resistors, or a large value RF, to keep the feed through current low enough to minimize the impact on the active channel. See the "Limitations of the Differential Input Protection" section for more details. Limitations of the Differential Input Protection If the input differential voltage is expected to exceed 0.5V, an external current limiting resistor must be used to ensure the input current never exceeds 5mA. For non-inverting unity gain applications, the current limiting can be via a series IN+ resistor, or via a feedback resistor of appropriate value. For other gain configurations, the series IN+ resistor is the best choice, unless the feedback (RF) and gain setting (RG) resistors are both sufficiently large to limit the input current to 5mA. Large differential input voltages can arise from several sources: 1) During open loop (comparator) operation. Used this way, the IN+ and IN- voltages don't track, so differentials arise. 2) When the amplifier is disabled but an input signal is still present. An RL or RG to GND keeps the IN- at GND, while the varying IN+ signal creates a differential voltage. Mux Amp applications are similar, except that the active channel VOUT determines the voltage on the IN- terminal. FN6153 FN6153.2 June 28, 2007 ISL28136 ISL28136, ISL28236 ISL28236 3) When the slew rate of the input pulse is considerably faster than the op amp's slew rate. If the VOUT can't keep up with the IN+ signal, a differential voltage results, and visible distortion occurs on the input and output signals. To avoid this issue, keep the input slew rate below 1.9V/s, or use appropriate current limiting resistors. Large (>2V) differential input voltages can also cause an increase in disabled ICC. Using Only One Channel The ISL28236 ISL28236 is a dual op amp. If the application only requires one channel, the user must configure the unused channel to prevent it from oscillating. The unused channel will oscillate if the input and output pins are floating. This will result in higher than expected supply currents and possible noise injection into the channel being used. The proper way to prevent this oscillation is to short the output to the negative input and ground the positive input (as shown in Figure 39). Power Dissipation It is possible to exceed the +125°C maximum junction temperatures under certain load and power-supply conditions. It is therefore important to calculate the maximum junction temperature (TJMAX) for all applications to determine if power supply voltages, load conditions, or package type need to be modified to remain in the safe operating area. These parameters are related as follows: T JMAX = T MAX + ( JA xPD MAXTOTAL ) (EQ. 1) where: · PDMAXTOTAL is the sum of the maximum power dissipation of each amplifier in the package (PDMAX) · PDMAX for each amplifier can be calculated as follows: V OUTMAX PD MAX = 2*V S × I SMAX + ( V S - V OUTMAX ) × -R L (EQ. 2) where: - · TMAX = Maximum ambient temperature + · JA = Thermal resistance of the package FIGURE 39. PREVENTING OSCILLATIONS IN UNUSED CHANNELS Current Limiting These devices have no internal current-limiting circuitry. If the output is shorted, it is possible to exceed the Absolute Maximum Rating for output current or power dissipation, potentially resulting in the destruction of the device. 12 · PDMAX = Maximum power dissipation of 1 amplifier · VS = Supply voltage (Magnitude of V+ and V-) · IMAX = Maximum supply current of 1 amplifier · VOUTMAX = Maximum output voltage swing of the application · RL = Load resistance FN6153 FN6153.2 June 28, 2007 ISL28136 ISL28136, ISL28236 ISL28236 SOT-23 Package Family MDP0038 MDP0038 e1 D SOT-23 PACKAGE FAMILY A MILLIMETERS 6 N SYMBOL 4 SOT23-5 SOT23-6 TOLERANCE A 0.15 C D 1 2X ±0.05 1.14 1.14 ±0.15 0.40 0.40 ±0.05 c 2X e 0.20 M C A-B D B b NX 0.14 0.14 ±0.06 2.90 2.90 Basic E 2.80 2.80 Basic E1 1.60 1.60 Basic e 3 D 0.95 0.95 Basic e1 2 0.20 C 5 MAX 0.10 A2 E 3 1.45 0.10 b E1 2 1.45 A1 1.90 1.90 Basic L 0.15 C A-B 1 0.45 ±0.10 0.60 0.60 Reference N 3 0.45 L1 5 6 Reference D 2X Rev.
