Overview
The ADAQ23876BBCZ is a high-performance, 16-bit, 15 MSPS (Mega Samples Per Second) µModule data acquisition solution developed by Analog Devices Inc. This device integrates multiple common signal processing and conditioning blocks into a single package, utilizing system-in-package (SIP) technology. It is designed to reduce the development cycle of precision measurement systems by combining a low noise, fully differential analog-to-digital converter (ADC) driver, a stable reference buffer, and a high-speed successive approximation register (SAR) ADC. This integration simplifies the design process by transferring the burden of component selection, optimization, and layout from the designer to the device itself.
