Overview
The ADA2200ARUZ, produced by Analog Devices Inc., is a synchronous demodulator and configurable analog filter. It is designed to perform precision magnitude and phase measurements in various applications, including industrial, medical, and communications. Utilizing Analog Devices' patented sampled analog technology (SAT), the ADA2200 processes signals entirely in the analog domain, eliminating quantization noise and rounding errors. This technology reduces the need for high ADC sample rates and offloads computationally heavy tasks from digital processors or microcontrollers.
