AD5734RBREZ

Overview

The AD5734RBREZ is a quad, 14-bit serial input, voltage output digital-to-analog converter (DAC) from Analog Devices. It operates from single supplies of +4.5 V to +16.5 V or dual supplies of ±4.5 V to ±16.5 V. The device features software-programmable output ranges including +5 V, +10 V, +10.8 V, ±5 V, ±10 V, and ±10.8 V. Key electrical specifications include a maximum integral nonlinearity (INL) of ±4 LSB, a maximum differential nonlinearity (DNL) of ±1 LSB, and a typical settling time of 10 µs. It integrates a ±5 ppm/°C reference, reference buffers, and power-up control circuitry.

Feature Summary

• Quad 14-bit resolution with guaranteed monotonicity
• Integrated internal reference with ±5 ppm/°C temperature coefficient
• Software-selectable unipolar/bipolar output voltage ranges
• Simultaneous updating via LDAC pin for all four channels

Applications

• Industrial automation systems
• Closed-loop servo control applications
• Process control instrumentation
• Automotive test and measurement equipment
• Programmable logic controllers

Procurement Notes

Verify the specific REEZ suffix against the manufacturer's current ordering guide to confirm package type and tape/reel configuration. Ensure compatibility with the required industrial temperature range of −40°C to +85°C for the target application environment.

Selection Notes

Select the AD5734R over the AD5724R or AD5754R based on the required 14-bit resolution. Confirm that the system requires an integrated reference; if not, the non-R variants may be considered. Verify that the serial interface timing meets the microcontroller or DSP clock requirements up to 30 MHz.

Part Context

The AD5734R belongs to the AD5724R/AD5734R/AD5754R family of complete, quad DACs. This family shares identical pinouts and functional architectures, differing primarily in resolution: 12-bit (AD5724R), 14-bit (AD5734R), and 16-bit (AD5754R). The 'R' designation indicates the inclusion of an on-chip precision reference.

Replacement Considerations

The AD5734AREZ is a pin-compatible alternative within the same family but lacks the internal reference. Substitution requires verifying external reference circuitry and ensuring performance parameters meet design constraints.
