Active: In Production.

Description

The DS1267 has two 256-position potentiometers, with wiper positions each set by stored 8-bit values. The DS1267 communicates through a 3-wire serial port interface that drives an internal control logic unit. Multiple DS1267s can be linked or daisy-chained for control by a single processor.

Digital potentiometers improve upon mechanical devices with processor control and programmability, greater reliability and accuracy, and packaging options that facilitate automatic assembly. This digital potentiometer offers extremely low-power use and reliable, accurate performance throughout the industrial temperature range.

The DS1267 is ideal for controlling the incoming signal levels in modems and for level adjustment and control of RF and audio signals in cellular telephones. Digital potentiometers are also used for battery charging and control circuitry, tuning and calibration, offset trimming of operational amplifiers, gain control, and power supply regulation.
