AD7820KPZ-REEL

Overview

The AD7820KPZ-REEL is an 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes a flash architecture and features a single-ended input type with one input channel. The device operates on a 5V supply for both analog and digital domains, supporting a parallel data interface. It is housed in a 20-PLCC package with J-leads, measuring 9x9 mm, and is designed for surface mount installation. The component functions as a sample-and-hold ADC with a 1:1 S/H to ADC ratio. It is rated for an operating temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Flash conversion architecture for high-speed digitization
• Integrated sample-and-hold functionality
• Parallel data output interface
• Single-ended input configuration

Applications

• General-purpose data acquisition systems
• Industrial process control monitoring
• Signal conditioning circuits requiring fast conversion

Procurement Notes

Verify the specific suffix 'REEL' against official Analog Devices documentation to confirm tape-and-reel packaging availability, as standard listings often indicate tube packaging for this part number. Confirm current lifecycle status, as distributors may list the component as discontinued or limited supply. Ensure the 20-PLCC footprint matches the target PCB design constraints before procurement.

Selection Notes

Select this component when an 8-bit resolution and parallel interface are required for cost-sensitive applications. Verify that the 5V supply voltage aligns with the system power rails. Consider the PLCC package size for board space limitations. Compare performance against newer serial interface ADCs if pin count reduction is a priority.

Part Context

This part belongs to the AD7820 family of 8-bit CMOS A/D converters from Analog Devices. The family includes variants such as the AD7820LRZ in SOIC-20 packaging. The KPZ suffix specifically denotes the 20-PLCC package style. These devices are designed for applications requiring moderate speed and resolution with direct parallel connectivity to microprocessors.
