The MAX5497ETE+ is a 10bit dual non-volatile linear taper digital potentiometer in 16 pin TQFN package. The device combines a single 1024 position potentiometer and the internal programmable voltage dividers and variable resistors perform the function of a mechanical potentiometer but replaces the mechanics with a pin-configurable 3-wire serial SPI compatible interface. It is a 2 terminal variable resistor which is ideally suited for applications requiring low temperature coefficient voltage dividers such as low-drift, programmable gain amplifiers.

• Supply voltage range is 2.7V to 5.25V (single supply operation)
