双路， 2MSPS ， 12位， 2 + 2或3 + 3通道，同步采样模拟数字转换器 Dual, 2MSPS, 12-Bit, 2 + 2 or 3 + 3 Channel, Simultaneous Sampling ANALOG-TO-DIGITAL CONVERTER

DESCRIPON

The ADS7863 is a dual, 12-bit, 2MSPS, analog-to-digital converter ADC with four fully differential or six pseudo-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 72dB at 100kHz, which is a critical performance characteristic in noisy environments.
