Overview
The AD73360LARZ is a six-input channel analog front-end processor designed by Analog Devices Inc. This device is tailored for general-purpose applications, including industrial power metering and multichannel analog inputs. It features six independent 16-bit analog-to-digital converter (ADC) channels, each providing a high signal-to-noise ratio (SNR) of 77 dB over a DC to 4 kHz signal bandwidth. The AD73360LARZ is particularly suited for applications requiring simultaneous sampling and low group delay, making it ideal for precise and synchronized data acquisition.
