The document describes the specifications and characteristics of the AD557 model, including resolution, relative accuracy, output ranges, output settling time, full-scale accuracy, zero error, monotonicity, etc. It also includes specifications for digital inputs and power supply.
The AD557 is an 8‑bit voltage‑switching digital‑to‑analog converter designed for low‑cost, high‑precision applications. It features internal reference, output amplifier, and logic connections, requiring only external selection of unipolar or bipolar output ranges.
The datasheet provides full electrical specifications, pin configurations for DIP and PLCC packages, timing diagrams, recommended grounding practices, and mechanical dimensions, enabling designers to integrate the device into micro‑computer systems and other precision analog circuits.
| Resolution | 8 Bits |
|---|---|
| Output Range (unipolar) | 0 V to 2.56 V |
| Operating Temperature | 0 °C – 70 °C |
| Zero Error | ±1 LSB |
The AD557 provides a 0 V to 2.56 V output range in unipolar mode.
The AD557 has an 8‑bit resolution.
Separate analog and digital grounds should be maintained and tied together at a single point to minimize noise.
