The TPL0501 device is a single-channel, linear-taper, digital potentiometer with 256 wiper positions. This device can be used as a three-terminal potentiometer or as a two-terminal rheostat. The TPL0501 is currently offered with end-to-end resistance of 100 kΩ. The internal registers of the TPL0501 can be accessed using a SPI-compatible interface. The TPL0501 has a nominal temperature coefficient of 35 ppm/°C.

The TPL0501 is available in 8-pin SOT-23 and
8-pin UQFN packages, with a specified temperature range of –40°C to +125°C.
