AD7820KRZ-REEL

Overview

The AD7820KRZ-REEL is an 8-bit CMOS analog-to-digital converter (ADC) from the AD7820 series, manufactured by Analog Devices Inc. It features a flash architecture with a single-ended input and parallel interface. The device operates on a 5 V analog and digital supply voltage, consuming 40 mW of power. It supports an external reference voltage of 4.75 V and functions within a temperature range of -40°C to +85°C. Packaged in an SOIC-20 surface-mount format, this component is designed for applications requiring high-speed conversion capabilities.

Feature Summary

• Flash architecture enables rapid analog-to-digital conversion processes.
• Parallel interface facilitates direct connection to microprocessors and logic systems.
• Single-ended input configuration simplifies signal interfacing requirements.

Applications

• High-speed data acquisition systems
• Industrial process control instrumentation
• Medical imaging equipment signal processing

Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits for reliable performance.

Selection Notes

Select this component when an 8-bit resolution and parallel interface are required for moderate-speed applications. Compare against SAR architectures if lower power consumption is critical, as flash types typically consume more energy. Verify that the 5 V supply voltage aligns with the system's power distribution network and that the SOIC-20 package fits the PCB layout constraints.

Part Context

This part belongs to the AD7820 family of 8-bit ADCs. Variants such as AD7820LRZ and AD7820KPZ offer similar electrical specifications but differ in package types like SOIC-20 or PLCC-20. The REEL suffix specifically denotes reel packaging for automated assembly, distinguishing it from tube-packaged equivalents.

Replacement Considerations

TLC0820AIFN is documented as a similar alternative. Verify pin compatibility and interface differences before substitution.
