DESCRIPTION
The TPL0102 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 TPL0102-100 has an
end-to-end resistance of 100kΩ.
The TPL0102 has non-volatile memory (EEPROM) which can be used to store the wiper position. 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.
