This document describes the features and characteristics of Analog Devices' AD7541A CMOS 12-Bit Monolithic Multiplying DAC. The product features an improved version of the AD7541 with full four-quadrant multiplication, 12-bit linearity, and compatibility with DTL/TTL/CMOS logic inputs.
The AD7541A is a 12‑bit multiplying digital‑to‑analog converter fabricated in a low‑noise CMOS process. It is offered in standard 18‑lead DIP and 20‑lead surface‑mount packages and is pin‑compatible with the original AD7541. The device provides full four‑quadrant multiplication, guaranteed monotonicity to 12 bits, and does not require external Schottky protection diodes.
Typical applications include precision instrumentation, signal generation, and control systems where high linearity and low offset are required. The datasheet includes detailed specifications, absolute maximum ratings, functional block diagrams, and recommended circuit configurations for both unipolar (2‑quadrant) and bipolar (4‑quadrant) operation.
