Overview
The AD8283WBCPZ-RL, produced by Analog Devices Inc., is a highly integrated radar receive path analog front-end (AFE) designed for low-cost, low-power, compact size, flexibility, and ease of use. This component is particularly suited for automotive radar applications, including adaptive cruise control and collision avoidance systems. It combines six channels of a low-noise preamplifier (LNA), a programmable gain amplifier (PGA), and an antialiasing filter (AAF), along with one direct-to-ADC channel, all integrated with a single 12-bit analog-to-digital converter (ADC).
