Overview
The AD9279BBCZ, produced by Analog Devices Inc., is a highly integrated, low-power, octal-channel analog-to-digital converter (ADC) system. This component is designed for applications requiring multiple channels of high-performance signal processing, such as medical ultrasound and automotive radar. It combines a low noise amplifier (LNA), a variable gain amplifier (VGA), an antialiasing filter (AAF), an ADC, and an I/Q demodulator with programmable phase rotation in a single package.
