TPL0202 - Texas Instruments

TPL0202 256-Taps Dual Channel Digital Potentiometer

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 an.
