3 Description

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.
