New High-Resolution Multiplying DACs Excel at Handling AC Signals

All digital-to-analog converters (DACs) provide an output proportional to the product of the digitally set gain and an applied reference voltage. A multiplying DAC differs from a fixed-reference DAC in that it can apply a high-resolution digitally set gain to a varying wideband analog signal. ADI’s new resistance-ladder multiplying DACs are inherently suitable for ac signal-processing applications.
