MAX5434PEZT-T中文资料美信数据手册PDF规格书

General Description

The MAX5432–MAX5435 nonvolatile, linear-taper, digital potentiometers perform the function of a mechanical potentiometer, but replace the mechanics with a simple 2-wire serial interface. Each device performs the same function as a discrete potentiometer or a variable resistor and has 32 tap points.
