描述The ADS8507 is a complete low power, single 5-V supply, 16-bit sampling analog-to-digital (A/D) converter. It contains a complete 16-bit capacitor-based, successive approximation register (SAR) A/D converter with sample and hold, clock, reference, and data interface. The converter can be configured for a variety of input ranges including ±10 V, 4 V,and 5 V. For most input ranges, the input voltage can swing to 25 V or -25 V without damage to the converter. ASPI compatible serial interface allows data to be synchronized to an internal or external clock. A full parallel interface with BYTE select is also provided to allow the maximum system design flexibility. The ADS8507 is specified at 40 kHz sampling rate over the industrial -40°C to 85°C temperature range.特性40-kHz Min SamplingRate4-V, 5-V, and ±10-V Input Ranges89.9-dB SINAD with 10-kHz Input±1.5 LSB Max INL+1.5/-1 LSB Max DNL, 16-Bit No Missing Codes±5-mV BPZ, ±0.4 PPM/°C BPZ DriftSPI Compatible Serial Output With Daisy-Chain (TAG) FeatureSingle 5-V Analog SupplyPin-Compatible With ADS7807 and 12-Bit ADS7806/8506Uses Internal or External 2.5-V ReferenceLow Power Dissipation24 mW Typ, 30 mW Max at 40 KSPS50-µW Max Power Down Mode28-Pin SO PackageFull Parallel Interface2's Comp or BTC Output CodeAPPLICATIONSIndustrial Process ControlTest EquipmentMedical EquipmentData Acquisition SystemsDigital Signal ProcessingInstrumentationQSPI, SPI are trademarks of Motorola.
