AD5307/AD5317/AD5327 are quad voltage output, 8/10/12-bit DACs in 16-lead TSSOP, with a working voltage range of 2.5 V to 5.5 V and a supply current of 400 μA. They have low power consumption, low noise and high precision.
The AD5307, AD5317, and AD5327 are quad buffered voltage‑output DACs offered in a 16‑lead TSSOP package. They operate from a single 2.5 V to 5.5 V supply and consume only 400 µA at 3 V. Each part includes rail‑to‑rail output buffers, power‑down capability, and a versatile 3‑wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards.
Key features include low‑power operation (down to 90 nA at 3 V), simultaneous output updates via LDAC, daisy‑chaining via SDO, and a temperature range of –40 °C to +105 °C. Detailed specifications, timing diagrams, pin functions, and absolute maximum ratings are provided for design reference.
