The ADS7863 is a dual, 12-bit, 1.5MSPS, 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 a critical performance characteristic in noisy environments.
