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.

2 Key Features
High Endurance: EEPROM up to 10M cycles
High Reliability: EEPROM up to 150 years data retention @ 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/ºC
Low-Power Standby Mode: 100nA
5MHz SPI-Compatible Serial Interface
Single-Supply Operation: +2.7 to +5.5V
TQFN 3x3mm 16-pin Package


APPLICATIONs
The device is ideal for mechanical potentiometer replacement, low-drift programmable gain amplifiers, audio volume control, LCD contrast control, and low-drift programmable filters.
