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.
