The AD5330/AD5331/AD5340/AD5341 are single 8-, 10-, and 12-bit DACs. They operate from a 2.5 V to 5.5 V supply consuming just 115 A 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, while the AD5330, AD5340, and AD5341 allow a choice of buffered or unbuffered reference input. The AD5330/AD5331/AD5340/AD5341 have a parallel interface. CS selects the device and data is loaded into the input registers on the rising edge of WR.
