Overview
The ADAQ7988BCCZ is a 16-bit analog-to-digital converter (ADC) μModule® data acquisition system designed by Analog Devices Inc. This integrated system combines several critical signal processing and conditioning blocks into a single system-in-package (SiP) design, making it highly versatile for various applications. The device includes a high accuracy, low power 16-bit successive approximation register (SAR) ADC, a low power, high bandwidth ADC driver, a low power stable reference buffer, and an efficient power management block. This integration simplifies the design process for data acquisition systems and reduces the PCB area by 50% compared to traditional designs.
