This document describes the features and performance of the AD73460 six-input channel analog front end, including 16-bit A/D converters, programmable input sample rate, 72 dB SNR, single supply operation, etc.
The AD73460 is a six-input channel analog front end processor designed for general-purpose applications such as industrial power metering or multichannel analog inputs. It integrates six 16-bit A/D conversion channels, each providing 72 dB signal-to-noise ratio, and features a programmable input gain amplifier with settings from 0 dB to 38 dB. The device supports synchronous sampling to ensure no phase delay between conversions and includes an on-chip 1.25 V reference voltage.
