AD5732RBREZ-REEL7

Overview

The AD5732RBREZ-REEL7 is a dual, 14-bit serial input digital-to-analog converter (DAC) from Analog Devices. It features software-programmable unipolar and bipolar output ranges including +5 V, +10 V, ±5 V, and ±10 V. The device integrates a precision reference with a maximum temperature coefficient of 5 ppm/°C and offers a typical settling time of 10 μs. Key accuracy specifications include an integral nonlinearity (INL) of ±4 LSB maximum and differential nonlinearity (DNL) of ±1 LSB maximum. It operates on single or dual supplies ranging from +4.5 V to +16.5 V analog and 2.7 V to 5.5 V digital, housed in a 24-lead TSSOP package.

Feature Summary

• Dual-channel 14-bit resolution with guaranteed monotonicity
• Integrated 2.5 V reference buffer with ±5 ppm/°C temperature coefficient
• Software-selectable output ranges: +5 V, +10 V, ±5 V, ±10 V
• Serial interface compatible with DSP/microcontrollers up to 30 MHz
• Simultaneous updating via LDAC and asynchronous CLR function

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 suffix REEL7 indicates tape-and-reel packaging when sourcing. Confirm the B-version performance specifications against current datasheet revisions. Ensure supply voltage constraints are met for the selected output range configuration. Check humidity sensitivity handling requirements during storage and assembly.

Selection Notes

Select this model for applications requiring dual channels with 14-bit precision and integrated references. Compare INL specifications against higher-resolution alternatives like the AD5752R if tighter linearity is required. Consider the AD5734R for quad-channel configurations. Verify power supply headroom requirements for the desired output voltage swing.

Part Context

This component belongs to the AD5722R/AD5732R/AD5752R family of complete, serial input DACs. It shares pin compatibility and functional architecture with the 12-bit AD5722R and 16-bit AD5752R variants. The family utilizes iCMOS process technology and supports both unipolar and bipolar operation modes within a standard industrial temperature range.

Replacement Considerations

The AD5732R without the internal reference is the direct predecessor. For quad-channel needs, the AD5734RBREZ is a compatible alternative. Higher resolution requirements may necessitate the AD5752RBREZ-REEL7.
