TPL0102-100PWR

The TPL0102 features two linear-taper digital potentiometers (DPOTs) with 256 tap positions each. Each voltage divider can be used as a three-terminal voltage divider or a two-terminal rheostat. The TPL0102-100 has an end-to-end resistance of 100kΩ. The TPL0102 includes non-volatile memory (EEPROM) for storing tap positions. This allows tap positions to be retained even during power loss, and automatically restored upon power-up. The internal registers of the TPL0102 are accessible via the I²C interface. The TPL0102 is available in a 14-pin MicroQFN and a 14-pin TSSOP package, rated for a temperature range of -40°C to 85°C.
