Digital potentiometer-10k-ohm-2-circuit-256-wiper-I2C-interface-10-MSOP

The CAT5112 is a single digit POT suitable for use as an electronic replacement for mechanical potentiometers. Ideal for automatic adjustments on high-volume production lines, but also in applications where equipment requiring periodic adjustments is difficult to access or located in hazardous or remote environments. The CAT5112 consists of a 32-tap series resistor array connected between the RH and RL terminals. Up/down counter and decoder controlled by three input pins to determine which tap is connected to the wiper RW. The CAT5112 wipers are buffered by rail-to-rail operational amplifiers. Wiper settings stored in non-volatile memory are not lost when power is removed from the device and are automatically recalled when power is restored. Wipers can be adjusted to test new system values ​​without affecting stored settings. The wiper control of CAT5112 is done through three input control pins CS, U/D and INC. The INC input advances the wiper in the direction determined by the logic state of the U/D input. The CS input is used to select the device and is also used to store the wiper position prior to power down. This 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 CAT5114. CAT5112 buffer wipers are not compatible with this application.
