This document is a functional block diagram of AD7837/AD7847, which introduces the overview, features and characteristics of the product.
The AD7837 and AD7847 are complete, dual, 12‑bit multiplying digital‑to‑analog converters with integrated output amplifiers on a single LC‑MOS chip. They support both 8‑bit and 16‑bit bus interfaces, provide +10 V output across a 2 kΩ load, and include internal laser‑trimmed compensation for low offset.
The document contains detailed specifications (resolution, accuracy, bandwidth, power requirements), timing characteristics, absolute maximum ratings, ordering information, pin descriptions for both DIP and SOIC packages, circuit diagrams, and example interface circuits for microprocessors such as the 6502/6809.
| Resolution | 12 bits |
|---|---|
| Differential Nonlinearity | +1 LSB max |
The commercial/industrial versions operate from –40 °C to +85 °C.
The DIP package has 24 leads.
