General Description
The AS1507 is a linear, dual 256-tap digital potentiome ter 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 features an internal EEPROM for storing wiper positions.
