Datasheet AD73360L (Analog Devices)

a
Six-Input Channel Analog Front End AD73360L FEATURES
metering or multichannel analog inputs. It features six 16-bit
Six 16-Bit A/D Converters
A/D conversion channels, each of which provides 76 dB signal-

channel also features a programmable input gain amplifier (PGA)
76 dB SNR
with gain settings in eight stages from 0 dB to 38 dB.
64 kS/s Maximum Sample Rate
The AD73360L is particularly suitable for industrial power
–95 dB Crosstalk
metering as each channel samples synchronously, ensuring that
Low Group Delay (25

s Typ per ADC Channel)
there is no (phase) delay between the conversions. The AD73360L
Programmable Input Gain
also features low group delay conversions on all channels.
Flexible Serial Port Which Allows Multiple Devices to Be Connected in Cascade
An on-chip reference voltage is included with a nominal value
Single (2.7 V to 3.6 V) Supply Operation
of 1.2 V.
80 mW Max Power Consumption at 2.7 V
The sampling rate of the device is programmable, with four
On-Chip Reference
separate settings offering 64 kHz, 32 kHz, 16 kHz, and 8 kHz
28-Lead SOIC Package
sampling rates (from a master clock of 16.384 MHz).
APPLICATIONS
A serial port (SPORT) allows easy interfacing of single or cas-
General-Purpose Analog Input
caded devices to industry-standard DSP engines. The SPORT
Industrial Power Metering
transfer rate is programmable to allow interfacing to both fast
Motor Control
and slow DSP engines.
Simultaneous Sampling Applications
The AD73360L is available in 28-lead SOIC package.
GENERAL DESCRIPTION
The AD73360L is a six-input channel analog front-end proces- sor for general-purpose applications, including industrial power
