ADAQ4224BBCZ

Overview

The ADAQ4224 is a 24-bit, 2 MSPS µModule data-acquisition solution integrating a programmable gain instrumentation amplifier (PGIA), anti-aliasing filter, ADC driver, and SAR ADC. It achieves a typical total system dynamic range of 128 dB with ±1 ppm maximum INL from −40°C to +105°C. The device features high-Z PGIA gains of 1/3, 5/9, 20/9, and 20/3, supporting differential input ranges up to ±15 V. It includes an isolated I2C temperature sensor and Flexi-SPI interface. Power dissipation is typically 446 mW at full throughput.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Confirm that the required supply voltages (VDDH, VSSH, VDD_5V) match the application design constraints before procurement.

Selection Notes

Select based on required input voltage range and gain settings. Ensure the host processor supports the Flexi-SPI interface modes (SDR/DDR) and logic levels (1.2 V to 1.8 V). Verify thermal management capabilities for the 14 mm × 9 mm CSP BGA package given the 446 mW power dissipation.

Part Context

This component belongs to Analog Devices' µModule precision data acquisition family. It consolidates signal chain components into a single System-in-Package (SIP) to reduce development time and board footprint compared to discrete solutions.
