AD5346/AD5347/AD5348 are a series of parallel interface octal voltage output 8-/10-/12-bit DACs with a voltage range of 2.5 V to 5.5 V. They feature low power operation, guaranteed monotonicity, rail-to-rail output range, power-on reset to 0 V, etc.
The AD5346, AD5347 and AD5348 are octal 8‑, 10‑ and 12‑bit digital‑to‑analog converters that operate from a 2.5 V to 5.5 V supply. They feature rail‑to‑rail output, optional buffered or unbuffered reference inputs, simultaneous update via an LDAC pin, and a power‑down mode with sub‑µA consumption. The devices are pin‑compatible, allowing designers to select the required resolution without redesigning the PCB.
The handbook provides detailed specifications (resolution, accuracy, power‑supply rejection, output voltage range, timing), absolute maximum ratings, pin configuration tables for both TSSOP and LFCSP packages, timing diagrams for the parallel interface, and ordering guides for each part number. Application examples include portable instruments, programmable voltage sources, and industrial process control.
