The Burr‑Brown PCM56 is a 16‑bit audio DAC that operates from ±5 V to ±12 V, offers low THD, high dynamic range, and optional MSB error adjustment.
The PCM56 is a fully self‑contained 16‑bit digital‑to‑analog converter designed for audio applications. It features a low‑noise internal zener reference, high‑speed current switches, a resistor ladder network, and a fast‑settling output op‑amp, all on a single monolithic chip. The device operates from ±5 V to ±12 V supplies and is available in 16‑pin plastic DIP or SOIC packages.
Key specifications include 96 dB dynamic range, –92 dB maximum THD at full‑scale input, 1.5 µs typical settling time, and optional external MSB error adjustment to further improve linearity. The datasheet provides detailed electrical characteristics, pinout, timing diagrams, and installation guidelines for reliable integration into digital audio systems.
| Resolution | 16‑bit |
|---|---|
| Dynamic Range | 96 dB |
| Maximum THD (FS Input) | -92 dB |
