DP7115 DP7115 32-Tap Digital Potentiometer (DP) DESCRIPTION FEATURES The DP7115 DP7115 is a single digital potentiometer (DP) designed as a electronic replacement for mechanical potentiometers and trim pots. Ideal for automated adjustments on high volume production lines, they are also well suited for applications where equipment requiring periodic adjustment is either difficult to access or located in a hazardous or remote environment. 32-position linear taper potentiometer Low power CMOS technology Single supply operation: 2.5V ­ 6V Increment up/down serial interface Resistance values: 10k , 50k and 100k Available in SOIC, TSSOP, MSOP and space saving 2 x 2.5mm TDFN packages The DP7115 DP7115 contains a 32-tap series resistor array connected between two terminals RH and RL. An up/down counter and decoder that are controlled by three input pins, determines which tap is connected to the wiper, RW. The wiper is always set to the mid point, tap 15 at power up. The tap position is not stored in memory. Wiper-control of the DP7115 DP7115 is ¯¯ ¯ accomplished with three input control pins, CS, U/D, ¯¯¯ ¯¯¯ and INC. The INC input increments the wiper in the direction which is determined by the logic state of the ¯ ¯¯ U/D input. The CS input is used to select the device. APPLICATIONS Automated product calibration Remote control adjustments Offset, gain and zero control Tamper-proof calibrations Contrast, brightness and volume controls Motor controls and feedback systems Programmable analog functions The digital potentiometer can be used as a three-terminal resistive divider or as a two-terminal variable resistor. DPs bring variability and programmability to a wide variety of applications including control, parameter adjustments, and signal processing. For Ordering Information details, see page 12. For a pin-compatible device that recalls a stored tap position on power-up refer to the DP7114 DP7114 data sheet.

When in a ¯¯¯ ¯ high state, activity on the INC and U/D inputs will not affect or change the position of the wiper. ¯ U/D: Up/Down Control Input ¯ The U/D input controls the direction of the wiper ¯¯ movement. When in a high state and CS is low, any ¯¯¯ will cause the wiper to high-to-low transition on INC move one increment toward the RH terminal. When in ¯¯ a low state and CS is low, any high-to-low transition ¯¯¯ will cause the wiper to move one increment on INC towards the RL terminal. DEVICE OPERATION The DP7115 DP7115 operates like a digital potentiometer with RH and R L equivalent to the high and low terminals and RW equivalent to the mechanical potentiometer's wiper. There are 32 available tap positions including the resistor end points, RH and RL. There are 31 resistor elements connected in series between the RH and RL terminals. The wiper terminal is connected to one of the 32 taps ¯¯¯ ¯ ¯¯ and controlled by three inputs, INC, U/D and CS. These inputs control a five-bit up/down counter whose output is decoded to select the wiper position. RH: High End Potentiometer Terminal RH is the high end terminal of the potentiometer. It is not required that this terminal be connected to a potential greater than the RL terminal. Voltage applied to the RH terminal cannot exceed the supply voltage, VCC or go below ground, GND. ¯¯ With CS set LOW the DP7115 DP7115 is selected and will ¯ ¯¯¯ respond to the U/D and INC inputs. HIGH to LOW ¯¯¯ will increment or decrement the transitions on INC ¯ wiper (depending on the state of the U/D input and five-bit counter). The wiper, when at either fixed terminal, acts like its mechanical equivalent and does not move beyond the last position. When the DP7115 DP7115 is powered-down, the wiper position is reset. When power is restored, the counter is set to the mid point, tap 15. RW: Wiper Potentiometer Terminal RW is the wiper terminal of the potentiometer. Its position on the resistor array is controlled by the ¯¯¯ ¯ ¯¯ control inputs, INC, U/D and CS. Voltage applied to the RW terminal cannot exceed the supply voltage, VCC or go below ground, GND. RL: Low End Potentiometer Terminal RL is the low end terminal of the potentiometer. It is not required that this terminal be connected to a potential less than the RH terminal. Voltage applied to the RL terminal cannot exceed the supply voltage, VCC or go below ground, GND. RL and RH are electrically interchangeable. Doc. No. MD-2117 MD-2117 Rev.
