The AD5512A/AD5542A is a single, 12-/16-bit, serial input, unbuffered voltage output digital-to-analog converter (DAC) that operates from 2.7 V to 5.5 V.
The AD5512A and AD5542A are single‑supply, 12‑/16‑bit, serial‑input, voltage‑output digital‑to‑analog converters (DACs) that operate from 2.7 V to 5.5 V. They provide unbuffered outputs with monotonic performance, low noise, and fast 1 µs settling time, making them suitable for precision instrumentation and high‑speed control.
The datasheet includes functional block diagrams, pin configurations, electrical specifications, timing characteristics, absolute maximum ratings, and typical performance graphs. Ordering information and package options (10‑lead LFCSP, 16‑lead LFCSP, 16‑lead TSSOP) are also provided.
