AD8582AN

Overview

The AD8582AN is a complete, parallel input, dual 12-bit voltage output digital-to-analog converter (DAC) designed for single +5 V operation. It integrates two DACs with rail-to-rail amplifiers, input registers, and a laser-trimmed 2.5 V bandgap reference. The device provides a full-scale output of 4.095 V with 1 mV/LSB resolution. Key electrical specifications include a settling time of 16 μs to ±1 LSB, INL/DNL of ±0.75 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 of –40°C to +85°C in a 24-pin plastic DIP package.

Feature Summary

• Dual 12-bit DACs with integrated rail-to-rail output amplifiers and internal 2.5 V reference
• Parallel data interface with double-buffered input structure for simultaneous or independent updates
• Asynchronous reset capability to zero scale or mid-scale via MSB pin
• Low power consumption of 5 mW typical with single +5 V supply

Applications

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

Procurement Notes

Verify the component status as the AD8582AN may be obsolete. Confirm the package type is 24-pin Plastic DIP (N-24). Ensure the operating temperature range meets requirements of –40°C to +85°C. Check for RoHS compliance if required by the design specification.

Selection Notes

Select this part for applications requiring a complete dual DAC solution without external components. It is suitable for systems strictly limited to a +5 V supply. Consider the 16 μs settling time and ±0.75 LSB linearity for precision requirements. Verify that the parallel interface timing matches the host processor capabilities.

Part Context

The AD8582AN belongs to the AD8582 series from Analog Devices. It is available in a 24-pin Plastic DIP (AD8582AN) and a 24-lead SOIC (AD8582AR) package. The device utilizes a CBCMOS process and contains 1270 transistors. It is distinct from other data converters like the AD7582 ADC or LT8582 DC/DC converter.
