ADI AD73360ARZ

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. The AD73360 is particularly suitable for industrial power metering as each channel samples synchronously, ensuring that there is no (phase) delay between the conversions. The AD73360 also features low group delay conversions on all channels. An on-chip reference voltage is included and is programmable to accommodate either 3V or 5V operation. The sampling rate of the device is programmable with four separate settings offering 64 kHz, 32 kHz, 16 kHz and 8 kHz sampling rates (from a master clock of 16.384 MHz). A serial port (SPORT) allows easy interfacing of single or cascaded 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-lead SOIC and 44-lead TQFP packages.
