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.

The AD73460 is particularly suitable for industrial power metering as each channel samples synchronously, ensuring that there is no (phase) delay between the conversions. The AD73460 also features low group delay conversions on all channels.
