GENERAL DESCRIPTION
AD865x family consists high precision, noise, distortion, rail-to-rail CMOS operational amplifiers that from single-supply voltage AD865x family made rail-to-rail input output amplifiers with gain bandwidth typical voltage offset across common mode from supply. also features noise-4.5 nV/Hz. AD865x family used communications applications, such cell phone transmission power control, fiber optic networking, wireless networking, video line drivers.
AD865x family features newest generation DigiTrim® in-package trimming. This generation measures corrects offset over entire input common-mode range, providing less distortion from variation than typical other rail-to-rail amplifiers. Offset voltage CMRR both specified guaranteed over entire common-mode range well over extended industrial temperature range. AD865x family offered narrow 8-lead SOIC package 8-lead MSOP package. amplifiers specified over extended industrial temperature range (-40°C +125°C).

DigiTrim technology achieve higher degree precision than available from most CMOS amplifiers. DigiTrim technology, used number Analog Devices amplifiers, method trimming offset voltage amplifier after been assembled. advantage post-package trimming that corrects offset voltages caused mechanical stresses assembly. AD865x family available standard pinouts, making DigiTrim completely transparent user. input stage amplifiers true rail-to-rail architecture, allowing input common-mode voltage range extend both positive negative supply rails. open-loop gain AD865x with load typically AD865x used precision application. amplifiers exhibit phase reversal common-mode voltages within power supply. With voltage noise nV/Hz -105 distortion kHz, signals, AD865x great choice high resolution data acquisition systems. Their noise, sub-pA input bias current, precision offset, high speed make them superb preamps fast photodiode applications. speed output drive capabilities AD865x also make amplifiers useful video applications. NMOS PMOS input stages separately trimmed using DigiTrim minimize offset voltage both differential pairs. Both NMOS PMOS input differential pairs active transition region when input commonmode voltage approximately below positive supply voltage. special design technique improves input offset voltage transition region that traditionally exhibits slight variation. result, common-mode rejection ratio improved within this transition band. Compared Burr Brown OPA350 amplifier, shown Figure AD865x, shown Figure exhibits much lower offset voltage shift across entire input common-mode range, including transition region.

Input Protection
with semiconductor device, condition exists input voltage exceed power supply, device input overvoltage characteristic must considered. inputs AD865x family protected with diodes either power supply. Excess input voltage energizes internal junctions AD865x, allowing current flow from input supplies. This results input stage with picoamps input current that withstand 4000 events (human body model) with degradation.

Bypassing schemes designed minimize supply impedance frequencies with parallel combination capacitors Chip capacitors (X7R NPO) critical should close possible amplifier package. tantalum capacitor less critical high frequency bypassing, and, most cases, only needed board supply inputs.
Grounding
ground plane layer important densely packed boards spread current-minimizing parasitic inductances. However, understanding where current flows circuit critical implementing effective high speed circuit design. length current path directly proportional magnitude parasitic inductances and, therefore, high frequency impedance path. High speed currents inductive ground return create unwanted voltage noise. length high frequency bypass capacitor leads critical. parasitic inductance bypass grounding works against impedance created bypass capacitor. Place ground leads bypass capacitors same physical location. Because load currents also flow from supplies, ground load impedance should same physical location bypass capacitor grounds. larger value capacitors, intended effective lower frequencies, current return path distance less critical.

Leakage Currents
Poor board layout, contaminants, board insulator material create leakage currents that much larger than input bias current AD865x family. voltage differential between inputs nearby traces sets leakage currents through board insulator, example V/100 Similarly, contaminants board create significant leakage (skin oils common problem). significantly reduce leakages, guard ring (shield) around inputs input leads that driven same voltage potential inputs. This ensures that there voltage potential between inputs surrounding area leakage currents. effective, guard ring must driven relatively impedance source should completely surround input leads sides, above below, using multilayer board. Another effect that cause leakage currents charge absorption insulator material itself. Minimizing amount material between input leads guard ring helps reduce absorption. Also, absorption materials, such Teflon® ceramic, necessary some instances.

Overdrive Recovery
Overdrive recovery defined time takes output amplifier come supply rail after overload signal initiated. This usually tested placing amplifier closedloop gain with input square wave while amplifier powered from either AD865x family excellent recovery time from overload conditions (see Figure Figure 32). output recovers from positive supply rail within supply voltages. Recovery from negative rail within supply.

Power Supply Bypassing
Power supply pins inputs noise, care must taken that noise-free, stable voltage applied. purpose bypass capacitors create impedances from supply ground frequencies, thereby shunting filtering most noise.

Input Capacitance
Along with bypassing grounding, high speed amplifiers sensitive parasitic capacitance between inputs ground. picofarads capacitance reduces input impedance high frequencies, which turn increases amplifier gain, causing peaking frequency response oscillations. With AD865x, additional input damping required stability with capacitive loads greater than with direct input output feedback (see Output Capacitance section). Another stabilize driving large capacitive load snubber network, shown Figure Because there isolation resistor signal path, this method significant advantage reducing output swing. exact values derived experimentally. Figure optimum combination capacitive load drive ranging from chosen. this, were chosen.
Output Capacitance
When using high speed amplifiers, important consider effects capacitive loading amplifier stability. Capacitive loading interacts with output impedance amplifier, causing reduction well peaking ringing frequency response. reduce effects capacitive loading allow higher capacitive loads, there commonly used methods. shown Figure place small value resistor (RS) series with output isolate load capacitor from amplifier output. Heavy capacitive loads reduce phase margin amplifier cause amplifier response peak become unstable. AD865x able drive unity gain buffer configuration without oscillation external compensation. However, application requires higher capacitive load drive when AD865x unity gain, external isolation networks used. effect produced this resistor isolate output from capacitive load. required amount series resistance been tabulated Table different capacitive loads. While this technique improves overall capacitive load drive amplifier, biggest drawback that reduces output swing overall circuit.
