Overview

The TPL0501 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 has an end–to-end resistance of 100kΩ. The internal registers of the TPL0501 can be accessed using a SPI-compatible interface. The TPL0501 has a nominal temperature coefficient of 35ppm/°C.

Features
  • Works with low cost MSP430 based LaunchPad platform
  • Simple GUI to control EVM
  • EVM can be operated in two different modes
  • Adjustable Voltage reference mode
  • Variable gain mode
  • Board is entirely powered by USB
