This document describes the features and characteristics of the 12-Bit High Speed Multiplying D/A Converter DAC312 produced by Analog Devices, including differential nonlinearity, nonlinearity, fast settling time, high compliance, differential outputs, guaranteed monotonicity, and low full-scale temperature coefficient.
The DAC312 is a 12‑bit multiplying digital‑to‑analog converter offering high speed, low power consumption (225 mW) and a wide compliance range of –5 V to +10 V. It combines a 9‑bit master D/A with a 3‑bit segment generator to achieve guaranteed monotonicity and low differential nonlinearity (≈6½ LSB). The device supports direct interfacing with TTL, CMOS, ECL, and other logic families via adjustable threshold control.
The manual details electrical characteristics, pin‑out options (20‑pin hermetic DIP, plastic DIP, SOL), ordering information, typical performance graphs, and application guidelines such as reference‑amplifier setup, output current handling, and temperature performance. It also includes safety notes on ESD sensitivity and recommended layout practices for optimal settling time (≈250 ns).
| Resolution | 12 Bits |
|---|---|
| Fast Settling Time | 250 ns |
| Power Consumption | 225 mW (typical) |
| Output Compliance | –5 V to +10 V |
| Differential Output Current | 0 to 4 mA |
The DAC312 typically settles within 250 ns to within ±½ LSB.
It operates over a supply range of +5 V/–11 V to ±18 V, with V+ = +5 V to +15 V and V– = –15 V.
Typical power consumption is 225 mW at the lower supply voltages.
The device provides output compliance from –5 V to +10 V.
