AD8582AR-REEL

Overview

The AD8582AR-REEL is a dual 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates from a single +5 V supply and features a parallel data interface with double-buffered input registers for simultaneous output updates. The device integrates a laser-trimmed 2.5 V bandgap reference, rail-to-rail output amplifiers, and DAC logic on a monolithic CBCMOS chip. It provides a voltage output range of 0 V to 4.095 V with 1 mV/LSB resolution and can drive loads up to ±5 mA. Key electrical specifications include a typical settling time of 16 μs to ±1 LSB, relative accuracy of ±3/4 LSB, and power dissipation as low as 5 mW.

Feature Summary

• Complete dual 12-bit DAC with integrated 2.5 V reference and rail-to-rail amplifiers
• Single +5 V supply operation with low power consumption (5 mW typical)
• Double-buffered input registers allow simultaneous update of both DAC outputs
• Asynchronous reset function sets outputs to zero or midscale

Applications

• Digitally controlled calibration systems
• Portable equipment requiring low power
• Servo control loops
• Process control equipment
• PC peripherals

Procurement Notes

Verify the package option matches the required form factor; the 'AR' suffix indicates the 24-lead SOIC package. Confirm the temperature range is –40°C to +85°C. Ensure the reel packaging aligns with automated assembly requirements. Check for ESD sensitivity precautions during handling.

Selection Notes

Select this component when a dual-channel, high-speed parallel DAC is needed with minimal external components. It is suitable for applications requiring a single +5 V supply and rail-to-rail output swing. Consider the 16 μs settling time and ±5 mA drive capability against load requirements. Verify that the parallel interface timing meets the microprocessor system constraints.

Part Context

The AD8582 is part of Analog Devices' complete DAC family designed for +5 V systems. The 'AR' designation specifies the surface-mount SOIC-24 package variant. The '-REEL' suffix denotes tape-and-reel packaging for high-volume manufacturing. It utilizes CBCMOS technology to combine low-power CMOS logic with precision bipolar analog circuits.
