3 Description

The TPL0102-EP is a two-channel, linear-taper digital potentiometer with 256 wiper positions. Each potentiometer can be used as a three-terminal potentiometer or as a two-terminal rheostat. The TPL0102-EP-100 has an end-to-end resistance of 100 kΩ.

The TPL0102-EP has non-volatile memory (EEPROM) which can be used to store the wiper position. The internal registers of the TPL0102-EP can be accessed using the I2C interface.

The TPL0102-EP is available in a 14-pin TSSOP package with a specified temperature range of –40°C to 125°C.
