AD73360 6-Channel AFE Processor for General Purpose Applications Including Industrial Power Metering or Multi-Channel Analog Inputs

The AD73360 is a six-channel analog input front-end processor for general purpose applications including industrial power metering or multi-channel analog inputs. It features six 16-bit A/D conversion channels each of which provide 77 dB signal-to-noise ratio over a voiceband signal bandwidth. It also features a programmable input gain amplifier (PGA) with gain settings in eight stages from 0 dB to 38 dB. The AD73360 is particularly suitable for industrial power metering as each channel samples synchronously ensuring that there is very little time (phase) delay between the conversions.

The AD73360 also features low group delay conversions on all channels. An on-chip reference voltage is included to allow single supply operation. This reference is programmable to accommodate either 3V or 5V operation. The sampling rate of the device is programmable with four separate settings offering 64, 32, 16 and 8 kHz sampling rates (from a master clock of 16.384 MHz). A serial port (SPORT) allows easy interfacing of single or cas-caded devices to industry standard DSP engines. The SPORT transfer rate is programmable to allow interfacing to both fast and slow DSP engines.

The AD73360 is available in 28-pin SOIC and 44-pin TQFP packages.
