AD7820LR-REEL

Overview

The AD7820LR-REEL is an 8-bit CMOS analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a single-channel, single-ended input architecture utilizing a flash conversion structure. The device operates with parallel digital interfaces and requires external voltage references. It supports standard 5 V analog and digital power supply voltages. The component is designed for surface-mount installation in SOIC-20 packages and functions within a commercial temperature range of -40°C to +85°C.

Feature Summary

• Flash architecture enables high-speed data conversion for real-time signal processing applications.
• CMOS technology ensures low power consumption while maintaining robust performance characteristics.
• Parallel interface facilitates direct connection to microprocessors and digital logic systems.

Applications

• Industrial process control systems requiring precise analog signal digitization
• Data acquisition modules for sensor interfacing
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'REEL' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with existing PCB footprints for SOIC-20 packages. Confirm that the operating temperature range meets system requirements. Validate that external reference circuits align with the device's input specifications.

Selection Notes

Select this component when an 8-bit resolution and parallel interface are required for cost-effective ADC solutions. Consider the flash architecture for speed requirements relative to other ADC types. Verify that the single-ended input configuration matches the source signal type. Evaluate power dissipation limits against available thermal management options on the target board.

Part Context

This part belongs to the AD7820 series of 8-bit ADCs from Analog Devices. The series includes various package options such as PDIP and PLCC. The LR variant specifically denotes the SOIC surface-mount package. The REEL suffix indicates bulk tape-and-reel shipping for automated assembly processes.

Replacement Considerations

Consult official Analog Devices documentation for qualified pin-compatible or functionally equivalent alternatives. Verify that any substitute maintains the same 8-bit resolution, flash architecture, and parallel interface timing requirements.
