AD5744R is a 14-bit high-precision serial input bipolar voltage output DAC introduced by Analog Devices. The chip has three programmable output ranges: ±10 V, ±10.2564 V, and ±10.5263 V. The output noise is 60 nV/√Hz, and the settling time is 10 μs. It has integrated reference buffers, internal reference, temperature sensor, short circuit protection, LDAC synchronous update, CLR asynchronous reset and other functions. It is suitable for industrial automation, open/closed loop servo control, process control, data acquisition systems and other fields.
The AD5744R is a quad, 14‑bit digital‑to‑analog converter that accepts a serial interface up to 30 MHz and provides bipolar voltage outputs. It features programmable output ranges (+10 V, +10.2564 V, +10.5263 V), integrated reference buffers, on‑chip temperature sensor, and digital offset/gain adjustment per channel. The device operates from ±11.4 V to ±16.5 V supplies and offers low noise (60 nV/V·Hz) and fast settling (10 µs max).
Typical applications include industrial automation, open‑ and closed‑loop servo control, process control, data acquisition systems, automatic test equipment, automotive test and measurement, and high‑accuracy instrumentation.
