    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.

    The ADS7863 is pin-compatible with the ADS7861, but offers additional features such as a programmable reference output, flexible supply voltage (2.7V to 5.5V for AVDD and BVDD), a pseudo-differential input multiplexer with three channels per ADC, and several power-down features.

    The ADS7863 is offered in an SSOP-24 and a 4×4mm QFN-24 package. It is specified over the extended operating temperature range of –40°C to +125°C.
