GENERAL DESCRIPTION OF THE ADSST-73360LAR 
ADC 
The ADSST-73360LAR is a 6-channel input 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 provides 76 dB 
signal-to-noise ratio over a dc to 4 kHz signal bandwidth. Each 
channel also features an input programmable gain amplifier 
(PGA) with gain settings in eight stages from 0 dB to 38 dB.  
The ADSST-73360LAR 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-73360LAR 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 ADSST-73360LAR is available in a 28-lead SOIC package.
