www.ti.com SNAS451A – FEBRUARY 2008 – REVISED MARCH 2013 ADC122S625 Dual 12-Bit, 50 kSPS to 200 kSPS, Simultaneous Sampling A/D Converter
Check for Samples: ADC122S625 FEATURES DESCRIPTION The ADC122S625 is a dual 12-bit, 50 kSPS to 200
kSPS simultaneous sampling Analog-to-Digital (A/D)
converter. The analog inputs on both channels are
sampled simultaneously to preserve their relative
phase information to each other. The converter is
based on a successive-approximation register
architecture where the differential nature of the
analog inputs is maintained from the internal trackand-hold circuits throughout the A/D converter to
provide excellent common-mode signal rejection. The
ADC122S625 features an external reference that can
be varied from 1.0V to VA. 1 23 True Simultaneous Sampling Differential
