GENERAL OVERVIEW

The AD5290 is a low cost, compact 2.9 mm × 3 mm

+30V/±±5V, 256-position digital potentiometer. This device

performs the same electronic adjustment function as

mechanical potentiometers or variable resistors, with enhanced

resolution, solid-state reliability, and superior low temperature

coefficient performance.

Figure 1.

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.

Note:

The terms digital potentiometer and RDAC are used interchangeably.

The AD5290 is available in ±0k, 50k, and ±00kΩ in compact
