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.
