GENERAL DESCRIPTION

The AD5160 provides a compact 2.9 mm × 3 mm packaged

solution for 256-position adjustment applications. These

devices perform the same electronic adjustment function as

mechanical potentiometers1 or variable resistors but with

enhanced resolution, solid-state reliability, and superior low

temperature coefficient performance.

The wiper settings are controllable through an SPI-compatible

digital interface. The resistance between the wiper and either

end point of the fixed resistor varies linearly with respect to the

digital code transferred into the RDAC latch.

Operating from a 2.7 V to 5.5 V power supply and consuming

less than 5 μA allows for usage in portable battery-operated

applications.

1 The terms digital potentiometer, VR, and RDAC are used interchangeably.
