General Description

The AS1507 is a linear, dual 256-tap digital potentiometer specifically designed to replace discrete/mechanical potentiometers and is ideal for applications requiring a low-temperature-coefficient variable resistor.

The device is controlled via a 3-wire SPI-compatible interface and
