3 Description

The TPL0102 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

TPL0102-100 has an end-to-end resistance of 100

kΩ.

The TPL0102 has non-volatile memory (EEPROM)

which can be used to store the wiper position. This is

beneficial because the wiper position is stored even

during power-off and is automatically reinstated after

power-on. The internal registers of the TPL0102 can

be accessed using the I2C interface.

The TPL0102 is available in a 14-pin MicroQFN and

14-pin TSSOP package with a specified temperature

range of –40°C to 85°C.
