Description
The AS1507 is a dual 256-tap digital potentiometer designed to replace discrete/mechanical potentiometers. It features an internal EEPROM for storing wiper positions and is controlled via a 3-wire SPI-compatible interface.
Features
High endurance: EEPROM up to 10M cycles
High reliability: EEPROM up to 150 years data retention at 85°C
Wiper position retained in EEPROM and loaded at power-up
256 tap positions
±0.5LSB DNL in voltage divider mode
±0.5LSB INL in voltage divider mode
End-to-end resistance: 10/50/100kΩ
Low end-to-end resistance temperature coefficient: 90ppm/°C
Low-power standby mode: 100nA
5MHz SPI-compatible serial interface
Single-supply operation: 2.7 to 5.5V
TQFN 3x3mm 16-pin package
Applications
Mechanical potentiometer replacement
Low-drift programmable gain amplifiers
Audio volume control
LCD contrast control
Low-drift programmable filters
