ADAQ4216BBCZ

Overview

The ADAQ4216BBCZ is a 16-bit, 2MSPS μModule data-acquisition solution manufactured by Analog Devices. It integrates a high-performance ADC, PGA, anti-aliasing filter, and reference buffer into a single 178-ball CSP BGA package measuring 14mm x 9mm with 0.8mm pitch. The device supports flexible external reference voltages of 4.096V or 5V and offers differential input voltage ranges including ±15V, ±9V, ±2.25V, and ±0.75V. It features a Flexi-SPI digital interface compatible with 1.2V to 1.8V logic and provides a total system dynamic range of 123dB typical.

• Structural health monitoring solutions

Part Context

The ADAQ4216BBCZ belongs to the ADQ421x family of μModule data-acquisition solutions. This series is designed to replace discrete component designs, offering a significant reduction in system footprint while maintaining high precision. The BBCZ suffix indicates specific performance grades and packaging configurations within the ADQ421x product line, tailored for industrial environments.

Replacement Considerations

Direct pin-to-pin replacements are not available due to the integrated nature of the μModule design. System redesigns may consider the ADQ4214 or ADQ4218 variants if channel count differences are acceptable. Discrete solutions using separate ADCs, PGAs, and filters can replicate functionality but require significantly more board space.
