DAC8248 - Analog Devices

DAC8248 Dual 12-Bit 8-Bit Byte Double-Buffered CMOS D/A Converter

The DAC8248’s double-buffered digital inputs allow both DAC’s analog output to be updated simultaneously. This is particularly useful in multiple DAC systems where a common LDAC signal updates all DACs at the same time. A single RESET pin resets both outputs to zero. The DAC8248’s monolithic construction offers excellent DACto-DAC matching and tracking over.
