AD7884APZ-REEL

Overview

The AD7884APZ-REEL is a 16-bit monolithic analog-to-digital converter featuring an internal sample-and-hold amplifier and a conversion time of 5.3 µs. It utilizes a two-pass flash architecture to achieve a maximum throughput rate of 166 kSPS. The device operates from ±5 V supplies with a 3 V reference input, supporting both ±5 V and ±3 V analog input ranges. It provides a 16-bit parallel data output structure in a 44-lead PLCC package.

Feature Summary

• Monolithic construction utilizing a two-pass flash architecture for high-speed operation
• Internal sample-and-hold amplifier with asynchronous CONVST initiation
• Integrated on-chip 16-bit accurate DAC for error correction
• Selectable analog input ranges of ±5 V or ±3 V

Applications

• Automatic Test Equipment
• Medical Instrumentation
• Industrial Control Systems
• Data Acquisition Systems
• Robotics

Procurement Notes

Verify the specific suffix 'P' indicates the 44-lead Plastic Leaded Chip Carrier (PLCC) package configuration. Confirm that the 'A' designation corresponds to the commercial temperature range of -40°C to +85°C. Ensure the reel packaging matches the REEL suffix requirement for automated assembly processes.

Selection Notes

Select this component when 16-bit resolution and high throughput are required. The two-pass flash architecture enables overlapping acquisition and conversion phases. Ensure the system design accommodates dual ±5 V power supplies and a precise 3 V reference source to maintain specified linearity and dynamic performance metrics.

Part Context

This part belongs to the AD7884/AD7885 family of LC2MOS high-speed sampling ADCs. The AD7884 variant specifically offers a full 16-bit parallel data word output, distinguishing it from the byte-read AD7885. Both share identical core conversion specifications and architectural features within the series.

Replacement Considerations

Public confirmed substitute part numbers: AD7884BP, AD7884AQ, AD7884BQ.
