AD7820KP-REEL

Overview

The AD7820KP-REEL is an 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes a half-flash architecture and features an integrated track-and-hold function with a 1:1 sampling ratio. The device operates on a single 5V supply for both analog and digital sections, supporting single-ended inputs via a parallel data interface. It is housed in a 20-pin PLCC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Half-flash architecture for high-speed conversion
• Integrated sample-and-hold circuit
• Single 5V power supply operation
• Parallel digital output interface

Applications

• High-speed data acquisition systems
• Industrial process control
• Medical instrumentation

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging rather than tube packaging when sourcing. Confirm RoHS compliance status as manufacturing processes evolve. Check current availability as this component may be subject to obsolescence or limited production runs.

Selection Notes

Select this part for applications requiring 8-bit resolution at high speeds with a parallel interface. Ensure the design accommodates the external reference voltage requirement. Verify that the 20-PLCC package footprint matches the PCB layout constraints.

Part Context

This component belongs to the AD7820 family of LC2MOS high-speed microprocessor-compatible ADCs. It shares architectural similarities with other members like the AD7821 and AD7822, differing primarily in resolution and speed specifications.
