GENERAL DESCRIPTION

The AD5332/AD5333/AD5342/AD5343 are dual 8-, 10-, and 12-bit DACs. They operate from a 2.5 V to 5.5 V supply consuming just 230 μA at 3 V, and feature a power-down pin, PD that further reduces the current to 80 nA. These devices incorporate an on-chip output buffer that can drive the output to both supply rails, while the AD5333 and AD5342 allow a choice of buffered or unbuffered reference input.
