Analog Devices DAC8248

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. The DAC8248’s monolithic construction offers excellent DACto-DAC matching and tracking over the full operating temperature range.

GENERAL DESCRIPTION

A single RESET pin resets both outputs to zero. The DAC consists of two thin-film R-2R resistor ladder networks, two 12-bit, two 8-bit, and two 4-bit data registers, and control logic circuitry. Separate reference input and feedback resistors are provided for each DAC. The DAC8248 (continued on page 4) The DAC8248 is a dual 12-bit, double-buffered, CMOS digitalto-analog converter.
