AD5725ARSZ-1REEL

Overview

The AD5725ARSZ-1REEL is a quad, 12-bit parallel input voltage output digital-to-analog converter manufactured by Analog Devices Inc. It features guaranteed monotonicity with an integral nonlinearity (INL) of ±0.5 LSB maximum and a differential nonlinearity (DNL) of ±1 LSB maximum. The device supports unipolar or bipolar operation with supply voltages ranging from +5 V to ±15 V. Key performance metrics include a maximum settling time of 10 µs for a 10 V step and power dissipation of less than 270 mW with ±15 V supplies. It operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Quad 12-bit resolution with ±0.5 LSB max INL error
• Parallel interface with double-buffered inputs and simultaneous updating via LDAC
• Asynchronous CLR function resets registers to zero scale (AD5725-1 variant)
• Readback capability for data verification

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 '1' in the part number AD5725ARSZ-1REEL against official documentation to confirm the asynchronous CLR behavior corresponds to zero scale reset rather than mid-scale. Confirm package type SSOP-28 and reel packaging specifications match project requirements before procurement.

Selection Notes

Select this component when a quad-channel DAC with high accuracy (±0.5 LSB INL) and fast settling time (10 µs) is required. Ensure the application utilizes a parallel interface compatible with the 12-bit data bus. Verify that the reference voltage configuration supports the desired unipolar or bipolar output ranges within the specified supply limits.

Part Context

This component belongs to the AD5725 family of high-performance digital-to-analog converters. The AD5725 series is designed for analog systems requiring higher voltage levels and precision. The specific part number indicates the B grade accuracy and the -1 suffix denotes the zero-scale reset characteristic for the CLR pin.
