2-Wire, 5-Bit DAC with Three Digital Outputs

General Description

Features

The DS4302 is a 5-bit digital-to-analog converter (DAC)

with three programmable digital outputs. The DS4302

communicates through a 2-wire, SMBus™-compatible,

serial interface. The tiny 8-pin µSOP package is ideal

for use in space-constrained applications.

♦ SO Package is a Drop-In Replacement for the

MPS1251 and MPS1252

♦ Single 5-Bit DAC (32 Steps)

♦ 0V to 2V and 0V to 1.9V Versions

♦ Three Programmable Digital Outputs

♦ SMBus-Compatible Serial Interface

♦ 4.5V to 5.5V Supply Voltage Range

♦ 8-Pin SO and 8-Pin µSOP Packages

♦ Industrial Temperature Range: -40°C to +85°C
