AD8582ANZ

Overview

The AD8582ANZ is a complete, dual 12-bit digital-to-analog converter designed for single +5 V operation. It integrates two voltage-output DACs with rail-to-rail amplifiers, input registers, and a laser-trimmed 2.5 V bandgap reference. The device features a parallel data interface compatible with high-speed processors without wait states. Key electrical parameters include a full-scale output of 4.095 V (1 mV/LSB), a typical settling time of 16 μs to ±1 LSB, and power dissipation of 35 mW. It operates within a supply range of +4.75 V to +5.25 V and supports an operating temperature range from –40°C to +85°C in a 24-pin plastic DIP package.

Feature Summary

• Dual 12-bit resolution with integrated 2.5 V internal reference and rail-to-rail output amplifiers
• Single +5 V supply operation with low power consumption of 5 mW typical
• Double-buffered parallel input structure allowing simultaneous or independent DAC updates
• Asynchronous reset capability to zero scale or mid-scale via MSB pin

Applications

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

Procurement Notes

Verify the specific ordering suffix 'ANZ' corresponds to the 24-pin Plastic DIP package and lead-free compliance as defined in the manufacturer's ordering guide. Confirm that the required operating temperature range of –40°C to +85°C aligns with the system environment. Ensure the parallel interface timing requirements, such as data setup and hold times, are met by the driving logic.

Selection Notes

Select this component when a dual-channel, voltage-output DAC is needed with no external components required for basic operation. The AD8582ANZ is suitable for applications demanding a single +5 V supply and direct processor interfacing. Consider the 16 μs settling time and 1 mV/LSB resolution against application accuracy needs. Verify that the 24-pin PDIP footprint fits the PCB layout constraints.

Part Context

The AD8582ANZ belongs to the AD8582 family of complete dual DACs. The 'A' suffix denotes the industrial temperature range (–40°C to +85°C), while 'N' indicates the 24-pin Plastic DIP package. The 'Z' suffix typically signifies lead-free packaging compliant with RoHS standards. Other variants include the SOIC-24 package option.

Replacement Considerations

The AD8582ARZ is a surface-mount equivalent using the SOIC-24 package with identical electrical specifications. Direct pin-compatible replacements should be verified against the datasheet for package dimensions and thermal characteristics.
