Functional Block Diagram GENERAL DESCRIPTION The ADSST-73360AR is a six-input channel analog front-end processor for power metering. It features six 16-bit A/D conver- sion provide 76 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 ADSST-73360AR is particularly suitable for industrial power metering as each channel samples synchronously, ensur- ing that there is no (phase) delay between the conversions. The ADSST-73360AR also features low group delay conversions on all channels. An on-chip reference voltage is included with a nominal value of 1.2 V. 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 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 ADSST-73360AR is available in 28-lead SOIC. |
