CAT5113ZI-00-T3 Datasheet PDF - ON Semiconductor

●The CAT5113 is a single digital POT designed as an 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 CAT5113 contains a 100-tap series resistor array connected between two terminals R. An up/down counter and decoder that are controlled by three input pins, determines which tap is connected to the wiper, R. The CAT5113 wiper is buffered by an op amp that operates rail to rail. The wiper setting, stored in non-volatile NVRAM 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 affecting the stored setting. Wiper-control of the CAT5113 is accomplished with three input control pins, input increments the wiper in the direction which is determined by the logic state of the U/ input is used to select the device and also store the wiper position prior to power down.The digital POT can be used as a three-terminal resistive divider or as a two-terminal variable resistor.
