NV, I C, Stepper Potentiometer

DS503

General Description

Features

The DS3503 features two synchronized stepping digital

potentiometers: one 7-bit potentiometer with RW as its

output, and another potentiometer with Y as its output.

Both potentiometers reference the RH and RL terminals

and feature an output voltage range of up to 15.5V. In

addition, both potentiometer outputs can be stepped

up and down by configuring the control registers.

♦ 128 Wiper Tap Points

♦ Full-Scale Resistance: 5kΩ

♦ Programmable Logic Lets WR Step Up and Down

with Timing Controlled by SYNC Input

♦ Second Potentiometer Output Pin (Y) Centered at

Position 40h

Programming is accomplished by an I C-compatible

♦ I C-Compatible Serial Interface

interface that can operate at speeds of up to 400kHz.

♦ Digital Operating Voltage: 2.7V to 3.6V

♦ Analog Operating Voltage: 4.5V to 15.5V

♦ Operating Temperature: -40°C to +100°C

♦ 10-Pin µSOP Package
