The TPL0202 has two linear-taper digital potentiometers (DPOTs) with 256 wiper positions. Each potentiometer can be used as a three-terminal potentiometer or as a two-terminal rheostat. The TPL0202-10 has an end-to-end resistance of 10 kΩ.
This DPOT can be used as a mechanical potentiometer replacement, allowing the user (or software) to digitally control and adjust resistance.
The TPL0202 has non-volatile memory (EEPROM) which can be used to store the wiper position for automatic recall upon power-up. The internal registers of the TPL0202 can be accessed using a SPI-compatible digital interface.
