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.
