Digital Potentiometer 256POS 50KOhm Dual 20-Pin TSSOP
Manufacturer Part #: DS1267BE-050+
Alternate Part #: DS1267BE-050+
The DS1267B has two 256-position potentiometers, with wiper positions each set by stored 8-bit values. The DS1267B communicates through a 3-wire serial port interface that drives an internal control logic unit. Multiple DS1267Bs can be linked or daisy-chained for control by a single processor. The DS1267B dual digital potentiometer replaces the DS1267, which has been discontinued. The device is designed for flexibility, operating from a single +5V or dual ±5V supply. Maximum standby current is only 2µA. Digital potentiometers improve upon mechanical devices with processor control and programmability, greater reliability and accuracy, and packaging options that facilitate automatic assembly. They are used for signal control in modems and phones, battery charging and control circuitry, tuning and calibration, offset trimming of operational amplifiers, gain control, and power-supply regulation.
