GENERAL DESCRIPTION

The AD73360 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 provide 77 dB signal-to-noise ratio over a dc to 4 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.
