AD8582ARZ-REEL

Overview

The AD8582ARZ-REEL is a complete dual 12-bit digital-to-analog converter 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 or independent DAC updates. The device integrates a laser-trimmed 2.5 V bandgap reference, rail-to-rail output amplifiers, and logic inputs. Key electrical specifications include a full-scale voltage of 4.095 V (1 mV/LSB), a typical settling time of 16 μs to ±1 LSB, and a maximum power dissipation of 35 mW. It is housed in a 24-lead SOIC package.

Feature Summary

• Complete dual 12-bit DAC with integrated 2.5 V reference and rail-to-rail amplifiers
• Parallel interface with double-buffered input registers allowing simultaneous output updates
• Low power consumption: 5 mW typical at +5 V supply
• True voltage output capable of driving ±5 mA loads

Applications

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

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the specific lot date code and manufacturing origin align with project requirements. Ensure ESD precautions are observed during handling as the device is sensitive to electrostatic discharge. Cross-reference the ordering information to confirm the SOL-24 package option matches the design footprint.

Selection Notes

Select this component for applications requiring a single +5 V supply and high-speed parallel data interfaces without wait states. The double-buffered architecture is suitable for systems needing synchronized multi-channel updates. Consider the 16 μs settling time and ±5 mA drive capability for load requirements. Verify that the 24-pin SOIC footprint fits the PCB layout constraints compared to the DIP alternative.

Part Context

The AD8582 series includes variants such as the AD8582AN (24-pin Plastic DIP) and AD8582AR (24-Lead SOIC). The AD8582ARZ-REEL specifically denotes the surface-mount SOIC version supplied in reel packaging. This part belongs to a family of complete, ready-to-use dual DACs designed for ease of integration in +5 V only systems using CBCMOS process technology.

Replacement Considerations

The AD8582AN serves as a pin-compatible through-hole alternative in a 24-pin DIP package. Designers transitioning from DIP to SOIC must account for the change in thermal resistance and physical footprint dimensions.
