DESCRIPTION
The
ADS7863
analog-to-digital converter (ADC) with four fully
differential input channels grouped into two pairs for
high-speed, simultaneous signal acquisition. Inputs
to the sample-and-hold (S/H) amplifiers are fully
differential and are maintained differential to the input
of the ADC. This architecture provides excellent
common-mode rejection of 80dB at 50kHz, which is
