DS4302 is a 5-bit digital-to-analog converter with three programmable digital outputs. DS4302 communicates through a 2-wire, SMBus™-compatible, serial interface. The tiny 8-pin µSOP package is ideal for use in space-constrained applications.
The DS4302 is a 5-bit digital-to-analog converter (DAC) featuring three programmable digital outputs. It communicates via a 2-wire, SMBus-compatible serial interface and is available in 8-pin SO and µSOP packages. The device offers 0V to 2V and 0V to 1.9V versions, making it suitable for space-constrained applications such as CCFL backlight brightness control and power-supply calibration.
