3 Description

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.
