AD7871KP-REEL

Overview

The AD7871KP-REEL is a single-channel, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates with a maximum sampling rate of 83 kSPS and features an internal reference voltage. The device supports both serial and parallel data access interfaces. It is housed in a 28-pin Plastic Leaded Crystal Carrier (PLCC) package, specifically the PQCC28 form factor. Electrical specifications include a maximum linear error of 0.0061% and a longest conversion time of 10.5 µs. The component is designed for operation with ±5 V power supplies.

Feature Summary

14-bit resolution with 83 kSPS sampling rate
Internal reference voltage eliminates external components
Flexible serial (SPI compatible) and parallel data output options
28-pin PLCC surface-mount package

Applications

Industrial process control systems requiring high accuracy
Data acquisition modules for scientific instrumentation
Vibration monitoring and acoustic analysis equipment

Procurement Notes

Verify the specific suffix 'KP' against current manufacturer documentation to confirm pinout compatibility and lead material specifications. Ensure the 'REEL' designation matches the required tape-and-reel quantity for automated assembly processes. Cross-reference humidity sensitivity level 3 requirements with storage and handling protocols before procurement.

Selection Notes

Select this component when a single-ended input SAR ADC with integrated reference is required. Compare the 83 kSPS speed against higher-speed alternatives if throughput demands exceed this limit. Verify that the 28-PLCC package footprint fits the target PCB layout constraints compared to smaller packages like SOIC or TQFP.

Part Context

This part belongs to the AD7871 family of 14-bit SAR ADCs. Variants such as AD7871JPZ and AD7871KNZ share similar electrical characteristics but differ in package type (PLCC vs. PDIP) and temperature range. The AD7871 series is distinct from the AD7851, which offers higher speed but lower resolution.
