AD5725ARSZ-500RL7

Overview

The AD5725ARSZ-500RL7 is a quad, 12-bit parallel input voltage output digital-to-analog converter manufactured by Analog Devices Inc. It operates from single or dual supplies ranging from +5 V to ±15 V. The device features guaranteed monotonicity with an integral nonlinearity (INL) of ±0.5 LSB maximum and differential nonlinearity (DNL) of ±1 LSB maximum. Key performance metrics include a maximum settling time of 10 µs for a 10 V step and a slew rate of 2.2 V/µs. It utilizes iCMOS process technology and includes double-buffered inputs, simultaneous updating via LDAC, and asynchronous CLR functionality.

Feature Summary

• Quad channel architecture with 12-bit resolution and parallel interface
• ±0.5 LSB max INL error and ±1 LSB max DNL error ensuring monotonic operation
• Wide supply range supporting +5 V to ±15 V operation
• Asynchronous CLR to zero/mid-scale and readback capability

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Ensure compatibility with system power supply rails and reference voltage configurations before integration. Cross-reference pin assignments with the official datasheet to prevent interface mismatches during PCB layout.

Selection Notes

Select this component when high accuracy and wide voltage operation are required for multi-channel applications. Verify that the parallel interface timing requirements align with the host controller capabilities. Consider the power dissipation limits relative to the ambient temperature and thermal impedance of the SSOP-28 package for proper heat management.

Part Context

This part belongs to the AD5725 family of high-performance DACs. It is distinguished by its parallel input interface and robust ±15 V supply capability compared to lower-voltage serial alternatives. The 'B' grade variant offers superior linearity specifications compared to the 'A' grade version.

Replacement Considerations

Direct replacements within the same family include the AD5725ARZ series. Verify functional equivalence regarding input register buffering and CLR behavior when substituting between grades or package variations.
