AD73360L

The AD73360L is a six-input channel analog front-end proces- or for general-purpose applications, including industrial powermetering or multichannel analog inputs. It features six 16-bit /D conversion channels, each of which provides 76 dB signal- o-noise ratio over a dc-to-4 kHz signal bandwidth. Ea chchannel also features a programmable input gain amplifier (PGA) with gain settings in eight stages from 0 dB to 38 dB.

The AD73360L is particularly suitable for industrial power metering as each channel samples synchronously, ensuring that there is no (phase) delay between the conversions. The AD73360L 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 AD73360L is available in 28-lead SOIC package.
