AD5722RBREZ-REEL7

Overview

The AD5722RBREZ-REEL7 is a dual, 12-bit serial input 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) error of ±1 LSB, a differential nonlinearity (DNL) error of ±1 LSB, and a typical settling time of 10 μs. It incorporates an integrated 2.5 V reference with a maximum temperature coefficient of 5 ppm/°C.

Feature Summary

• Dual-channel 12-bit resolution with guaranteed monotonicity
• Integrated 2.5 V reference buffer with 5 ppm/°C maximum drift
• Software-selectable unipolar and bipolar output voltage ranges
• DSP-compatible serial interface supporting clock rates up to 30 MHz

Applications

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

Procurement Notes

Verify the REEL7 suffix indicates tape-and-reel packaging containing 1000 units per reel. Confirm the B version designation aligns with specific AC performance requirements such as settling time and glitch energy. Ensure compatibility with the 24-lead TSSOP footprint during PCB layout planning.

Selection Notes

Select this component for applications requiring high-voltage analog outputs driven by low-voltage digital logic. The iCMOS process technology supports operation at supply voltages up to ±16.5 V while maintaining low power consumption. Consider the AD5732R or AD5752R if higher resolution (14-bit or 16-bit) is required for the same form factor.

Part Context

This part belongs to the AD5722R/AD5732R/AD5752R family of complete, dual, serial input DACs. It utilizes iCMOS process technology to combine high-voltage capabilities with low-power consumption. The device is pin-compatible with the non-R versions (AD5722), which lack the internal reference, allowing for design flexibility across the product line.

Replacement Considerations

The AD5722AREZ is a pin-compatible alternative within the same family but lacks the internal reference. For quad-channel configurations, the AD5724R serves as a functional expansion option. Verify that any substitute maintains the required 24-lead TSSOP package dimensions and thermal characteristics.
