AD5302/AD5312/AD5322 is a dual rail-to-rail voltage output 8-/10-/12-bit DAC with a voltage range of 2.5V to 5.5V and a current of 230μA. It features dual rail-to-rail output and micropower operation.
The AD5302/AD5312/AD5322 family are dual 8‑, 10‑ and 12‑bit buffered voltage‑output DACs in a 10‑lead MSOP package. They operate from a single 2.5 V to 5.5 V supply, provide rail‑to‑rail outputs, and feature a low‑power serial interface compatible with SPI, QSPI, MICROWIRE and DSP standards.
The document includes detailed specifications, timing characteristics, absolute maximum ratings, pin descriptions, typical performance graphs, outline dimensions and an ordering guide. Automotive‑qualified versions are also listed, with separate part numbers for RoHS‑compliant and automotive‑grade devices.
| Supply voltage range | 2.5 V to 5.5 V |
|---|---|
| Normal‑mode current consumption | 300 µA @ 5 V |
| Power‑down current | 200 nA @ 5 V, 50 nA @ 3 V |
| Serial interface speed | up to 30 MHz clock rate |
The devices operate from a single supply of 2.5 V to 5.5 V.
Typical current consumption is 300 µA when powered at 5 V.
In power‑down mode the current drops to 200 nA at 5 V or 50 nA at 3 V.
