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.
