MAX5422 Datasheet Digital Potentiometers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: www.DataSheet.co.kr 19-3371; Rev 0; 7/04 256-Tap, Nonvolatile, SPI-Interface, Digital.

General Description

The MAX5422/MAX5423/MAX5424 nonvolatile, lineartaper, digital potentiometers perform the function of a mechanical potentiometer, but replace the mechanics with a simple 3-wire SPI™-compatible digital interface.

Each device performs the same function as a discrete potentiometer or variable resistor and has 256 tap points.
