The ADS8365architecture provides excellent common-mode rejection of 80dB at 50kHz—ideal for high-noiseenvironments. It also includes a high-speed parallel interface with a direct address mode, acycle and a FIFO mode.Ch A0+Ch A0–Hold ACh A1+Ch A1–Ch B0+Ch B0–Hold BCh B1+Ch B1–Ch C0+Ch C0–Hold CS/HAmp 1S/HAmp 2S/HAmp 3S/HAmp 4S/HAmp 5ADC 1Ref BufferRef BufferADC 2ADC 3ADC 4ADC 5Ref BufferADS8365InterfaceConversionandControlFIFORegister6xA0A1A2ADDNAPRDWRCSFDEOCCLKRESETBYTEDATAINPUT/OUTPUTCh C1+Ch C1–S/HAmp 6ADC 6REFINREFOUTInternal2.5VReferenceIntelligent Fan Controller with I 2 C InterfaceAMC6821ADS8365 functional block diagram.Get samples, datasheets, evaluation modules and app reports at: www.ti.com/sc/device/AMC6821Key Features• Remote/local temperature sensor range:• +50°C to +100°C, ±1°C• –25°C to +125°C, ±3°C• Resolution: 0.125°C• PWM controller• Frequency: 10 to 40kHz• Duty cycle: 0 to 100%, 8-bits• Automatic fan speed control loops• SMB interface• Power: 2.7V to 5.5V• Packaging: QFN-16 (4x4mm), SSOP-16Applications• Notebook PCs• Network servers• Desktop PCs• Telecommunication equipment• PC-based equipmentThe AMC6821 is an analog interface circuit with an integrated temperature sensor to measurethe ambient temperature and one remote diode sensor input to measure external (CPU)temperature—ideal for notebook and desktop PC applications.

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.
