GENERAL DESCRIPTION
The AD73360L is a six-input channel analog front-end proces-
sor 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 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 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.
