MAX5487PMB1：MAX5487PMB1 Peripheral Module

The MAX5487PMB1 peripheral module provides the necessary hardware to interface the MAX5487 dual linear-taper digital potentiometer to any system that utilizes Pmod™-compatible expansion ports configurable for SPI communication. These digital potentiometers function like mechanical potentiometers with a simple 3-wire SPI-compatible interface that programs the wipers to any one of 256 tap positions. The terminals of each potentiometer are available at the output connector for attachment to external circuitry. Refer to the MAX5487/MAX5488/MAX5489 IC data sheet for detailed information regarding operation of the IC.
