GENERAL DESCRIPTION
The AD5334/AD5335/AD5336/AD5344 are quad 8-, 10-, and 12-bit DACs. They operate from a 2.5 V to 5.5 V supply consuming just 500 µA at 3 V, and feature a power-down mode 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.
