ADSST-SALEM-3T

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.
