DS3903 - Triple 128-Position Nonvolatile Digital Potentiometer

DS3903 Description

www.DataSheet4U.com Rev 0; 6/02 Triple 128-Position Nonvolatile Digital Potentiometer General .
The DS3903 contains three nonvolatile (NV) low temperature coefficient digital potentiometers, which can be accessed through a 2-wire bus.

DS3903 Features

* a write-protect pin that can lock the positions of the potentiometers. An address pin allows two DS3903s to be placed on the same 2-wire bus. Features
* Three 128-Position Linear Potentiometers (Two 10kΩ, One 90kΩ)
* NV Wiper Storage
* 0 to 5.5V on Any Potentiometer Terminal

DS3903 Applications

* Power-Supply Calibration Mobile Phones and PDAs Fiber Optics Transceiver Modules Portable Electronics A Small, Low-Cost Replacement for Mechanical Potentiometers Ordering Information PART TEMP RANGE -40°C to +85°C -40°C to +85°C PIN-PACKAGE 20 TSSOP 20 TSSOP (Tape-and-Reel) e DataShe DataSheet4U.
