2-Wire, 5-Bit DAC with Three Digital Outputs
General Description
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.
Features
♦ 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
