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 device is currently offered with end-to-end resistance of 100 kΩ. The internal registers of the TPL0501 device can be accessed using a SPI-compatible interface. The TPL0501 device has a nominal temperature coefficient of 35 ppm/°C.
The TPL0501 is available in an 8-pin SOT-23 and 8-pin UQFN package with a specified temperature range of –40°C to 85°C.
