The ADS7864 is a dual 12-bit, 500kHz Analog-to-Digital (A/D) converter with 6 fully differenTIal inputchannels grouped into three pairs for high speed simultaneoussignal acquisiTIon. Inputs to the sample-andholdamplifiers are fully differenTIal and are maintaineddifferenTIal to the input of the A/D converter.This provides excellent common-mode rejection of80dB at 50kHz which is important in high noiseenvironments.The ADS7864 offers a parallel interface and controlinputs to minimize software overhead. The output datafor each channel is available as a 16-bit word (addressand data). The ADS7864 is offered in a TQFP-48package and is fully specified over the –40°C to +85°Coperating range.
