Description

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. The TPL0501 is available in an 8-pin SOT-23 and 8-microQFN package with a specified temperature range of -40°C to +125°C.

The TPL0501EVM is designed to operate with the Texas Instruments LaunchPad (MSP-EXP430G2). The TPL0501EVM comes with a pre-programmed MSP430G2553 microcontroller which is to be inserted in the DIP socket on the LaunchPad. The LaunchPad can be purchased separately at http://www.ti.com/launchpad

The TPL0501EVM has two different evaluation modes:

Mode 1 – Adjustable voltage reference mode – in this mode the TPL0501 is used in conjunction with an LMV321 op amp as an adjustable voltage reference circuit.

Mode 2 – Variable gain mode – in this mode the TPL0501 is configured as part of a variable gain non-inverting amplifier. The gain of the amplifier can be controlled by a digital interface. This mode can be used to evaluate the bandwidth of the TPL0501.

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
