Overview
The AD8284WCSVZ-RL, produced by Analog Devices Inc., is an integrated analog front end (AFE) designed for automotive radar and other high-performance applications. This device combines a 4-channel differential multiplexer (mux), a low noise preamplifier (LNA) with a programmable gain amplifier (PGA), an antialiasing filter (AAF), and a 12-bit analog-to-digital converter (ADC). It is optimized for low cost, compact size, flexibility, and ease of use, making it ideal for applications where dynamic performance and low power consumption are critical.
