DESCRIPTION
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. The ADS7863 is pin-compatible with the ADS8361, but offers additional features such as a programmable reference output, flexible supply voltage (2.7V to 5.5V for AVDD and 1.65V to 5.5V for BVDD), a pseudo-differential input multiplexer with three channels per ADC, and several power-down features. The high-speed, dual serial interface is also pin-compatible with the ADS7861 while offering additional flexibility. The ADS7863 is offered in an SSOP-24 and a 4x4mm QFN-24 package. It is specified over……
