MAXIM INTEGRATED PRODUCTS  MAX5497ETE+  非易失性数字电位器, 50 kohm, 双, SPI, 线性, ± 25%, 2.7 V

The 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.
