The document describes the AD7394, a dual, 12-bit serial input DAC, which operates from a single 3V supply. It features micropower consumption, single-supply operation, high resolution, etc.
The AD7394 is a dual, 12‑bit voltage‑output digital‑to‑analog converter designed for single‑supply operation from 2.7 V to 5.5 V. It offers a rail‑to‑rail output, low power consumption, and a serial data interface with Schmitt‑triggered inputs.
Key features include micropower shutdown (0.1 pA typ), source and sink output currents of 1 mA and 3 mA respectively, and a compact 14‑lead SOIC package suitable for battery‑operated applications.
| Supply Voltage Range | 2.7 V to 5.5 V |
|---|---|
| Power‑down Current (SHDN) | 0.1 pA typ |
| Output Source Current | 1 mA typ |
| Output Sink Current | 3 mA typ |
| Differential Nonlinearity (DNL) | +0.9 LSB max |
| Package | 14‑Lead SOIC (R‑14) |
The AD7394 operates from a single supply of 2.7 V to 5.5 V.
In shutdown mode the device draws as little as 0.1 pA typical.
It uses a serial interface with Schmitt‑triggered inputs (SDI, CLK, LDA/LDB).
The device is offered in a 14‑lead standard small‑outline SOIC (R‑14) package.
