AD5725BRSZ-REEL

Overview

The AD5725BRSZ-REEL is a quad, 12-bit parallel input voltage output digital-to-analog converter manufactured by Analog Devices Inc. It features guaranteed monotonicity with a maximum integral nonlinearity (INL) of ±0.5 LSB and a maximum differential nonlinearity (DNL) of ±1 LSB. The device supports operation from single +5 V to dual ±15 V supplies, utilizing iCMOS process technology for low power consumption. 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 incorporates double-buffered inputs, simultaneous updating via LDAC, and asynchronous CLR functionality.

Feature Summary

• Quad 12-bit resolution with ±0.5 LSB max INL and ±1 LSB max DNL
• Wide supply range: Single +5 V to Dual ±15 V operation
• Parallel interface with readback capability and double-buffered inputs
• Asynchronous CLR to zero/mid-scale and simultaneous LDAC update

Applications

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

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging when sourcing. Confirm the specific grade (A or B) required for INL specifications, as the base part number may denote different accuracy grades. Ensure the ordering information matches the exact package type and temperature range specified in the manufacturer's current documentation.

Selection Notes

Select this component for applications requiring four independent 12-bit channels with high voltage swing capabilities. The parallel interface requires careful timing management regarding CS, R/W, and address lines. Consider the power dissipation limits, which reach up to 270 mW with ±15 V supplies, and ensure adequate thermal management within the SSOP-28 package.

Part Context

The AD5725 belongs to Analog Devices' portfolio of high-performance data converters designed for industrial environments. It utilizes iCMOS technology to achieve analog performance at higher voltage levels while maintaining reduced power consumption. This series is distinct from serial input DACs, offering faster parallel data throughput suitable for real-time control loops.
