DESCRIPTION
The TPL0202 is a two channel, linear-taper digital potentiometer 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 10kΩ.
The TPL0202 has non-volatile memory (EEPROM) which can be used to store the wiper position. The internal
registers of the TPL0202 can be accessed using a SPI-compatible digital interface.
The TPL0202 is available in a 14-pin MicroQFN (2mm x 2mm) and 16-pin QFN (3mm x 3mm) package with a
specified temperature range of -40°C to +85°C.
