Inputs to the sample-and-holdamplifiers are fully differential and are maintained differential to the input of the A/D converter.This provides excellent common-mode rejection of 80dB at 50kHz which is important in highnoise environments. The ADS7863 offers a high-speed, dual serial interface and control inputsto minimize software overhead.Applications• Motor control• Multi-axis positioning systems• 3-phase power controlCH A0+CH A0–CH A1+CH A1–REFINREFOUTCH B0+CH B0–SHASHAInternal2.5VReferenceCDACSARCOMPADS7863COMPSerialInterfaceSERIAL DATA ASERIAL DATA BM0M1A0CLOCKCSRDBUSYCONVSTCDACSee page 29 fora completeselection of analogcurrent shunt monitors.CH B1+CH B1–ADS7863 functional block diagram. *Expected release date 4Q 2007.SARAnalog Monitoring and Control Selection GuideSample Number ofRes.
