AD7820KPZ

Overview

The AD7820KPZ 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 configuration with a parallel data interface. The device operates on a 5V supply for both analog and digital sections, supporting a reference voltage of 4.75V. It is housed in a 20-PLCC package measuring 9x9 mm and supports 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 operation within a temperature range of -40°C to +85°C.

Feature Summary

Flash conversion architecture for high-speed digitization
Integrated sample-and-hold circuitry
Parallel digital output interface
Single-ended input signal processing

Applications

General-purpose data acquisition systems
Industrial control applications requiring fast sampling
Signal processing circuits utilizing parallel interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for end-of-life notices, as the part may be discontinued or restricted. Ensure the 20-PLCC package matches the target PCB footprint and that the 5V logic levels are compatible with the system design.

Selection Notes

Select this component when an 8-bit resolution and flash architecture are required for parallel data output. Verify that the 20-PLCC surface-mount package fits the assembly constraints. Ensure the system can accommodate the external reference voltage requirement and that the operating temperature range meets the environmental specifications.

Part Context

This component belongs to the AD7820 series of 8-bit ADCs from Analog Devices. It shares architectural similarities with other parts in the family but differs in packaging and specific pinout configurations. The KPZ suffix specifically denotes the 20-PLCC plastic leaded chip carrier package variant.
