描述The ADS8505 is a complete 16-bit sampling A/D converter using state-of-the-art CMOS structures. It contains a complete 16-bit, capacitor-based, SAR A/D with S/H, reference, clock, interface for microprocessor use, and 3-state output drivers. The ADS8505 is specified at a 250-kHz sampling rate over the full temperature range. Precisionresistors provide an industry standard ±10-V input range, while the innovative design allows operation from a single +5-V supply, with power dissipation under 100 mW. The ADS8505 is available in 28-pin SOIC and 28-pin SSOP packages, both fully specified for operation over the industrial -40°C to 85°C temperature range.特性105dB SFDR at 250-kHz Sample RateStandard ±10-V Input Range±1.5 LSB Max INL±1 LSB Max DNL, 16-Bits No Missing Codes±2 mV Max Bipolar Zero Error With ±0.4 PPM/°C Drift±0.1% FSR Max Full-Scale Error With ±2 PPM/°C DriftSingle 5-V Supply OperationPin-Compatible With ADS7805 (Low Speed) and 12-Bit ADS8504/7804Uses Internal or External ReferenceFull Parallel DataOutput70-mW Typ Power Dissipation at 250 KSPS28-Pin SSOP and SOIC PackagesAPPLICATIONSIndustrial Process ControlData Acquisition SystemsDigital Signal ProcessingMedical EquipmentInstrumentation
