GENERAL DESCRIPTION
The AD73460 is a six-input channel analog front-end processor for general-purpose applications including industrial power metering or multichannel analog inputs. It features six 16-bit A/D conversion channels, each of which provides 72 dB signal-to-noise ratio over a dc-to-2 kHz signal bandwidth. Each channel also features a programmable input gain amplifier (PGA) with gain settings in eight stages from 0 dB to 38 dB.
