Overview
The AD9271BSVZRL-40, produced by Analog Devices Inc., is a highly integrated, octal-channel analog-to-digital converter (ADC) designed for applications requiring low power, small size, and high dynamic performance. This device combines eight channels of a low noise preamplifier (LNA), a variable gain amplifier (VGA), an antialiasing filter (AAF), and a 12-bit ADC. It is optimized for use in medical imaging, ultrasound, and automotive radar systems, among others.
