Overview
The AD7884BPZ-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 Plastic Leaded Chip Carrier (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 residue error correction
- Selectable analog input ranges of ±5 V or ±3 V via dedicated force/sense pins
Applications
- Automatic Test Equipment
- Medical Instrumentation
- Industrial Control Systems
- Data Acquisition Systems
- Robotics
Procurement Notes
Verify the specific suffix 'P' corresponds to the 44-lead PLCC package configuration as defined in the manufacturer's ordering guide. Confirm that the 'B' designation indicates the specified linearity and temperature error characteristics. Ensure the reel packaging matches the required quantity specifications for the production environment.
Selection Notes
Select this component when a 16-bit resolution and 166 kSPS throughput are required. The device necessitates dual ±5 V power supplies and a precise 3 V reference source. Consider the parallel interface requirements and the specific pinout of the 44-lead PLCC package during PCB layout design.
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-oriented AD7885. The BP suffix denotes a specific grade within the commercial temperature range offering enhanced linearity performance.
