The TPL0102-EP is a 256-tap dual-channel digital potentiometer (digipot) with non-volatile memory
The TPL0102-EP is an ADM809TAKS-REEL7 dual-channel linear tapered digital potentiometer with 256 wiper positions. Each potentiometer can be used as a three-terminal potentiometer or a two-terminal rheostat. The end-to-end resistance of the TPL0102-EP is 100 kΩ.
The TPL0102-EP has non-volatile memory (EEPROM) that can be used to store wiper positions. The internal registers of the TPL0102-EP can be accessed using the I 2 C interface.
The TPL0102-EP is available in a 14-pin TSSOP package and is specified over the –40°C to 125°C temperature range.
