DP7112 32-Tap Digital Potentiometer (DP) with Buffered Wiper
electronic replacement for mechanical potentiometers. 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. The DP7112 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, RWB. The DP7112 wiper is buffered by an op amp that operates rail to rail. The wiper setting, stored in nonvolatile memory, is not lost when the device is powered down and is automatically recalled when power is returned. The wiper can be adjusted to test new system values without effecting the stored setting.
Wiper-control of the DP7112 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 and also store the wiper
position prior to power down.
The digital potentiometer can be used as a buffered voltage
divider. For applications where the potentiometer is used as a 2-terminal variable resistor, please refer to the DP7114. The buffered wiper of the DP7112 is not compatible with that application.
