描述The ADS8513 is a complete low-power, single 5V 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 serial data interface. The converter can be configured for a variety of input ranges including ±10 V, ±5V, 0V to 10V, and 0.5V to 4.5V. A high-impedance, 0.3V to 2.8V input is also available with input impedance greater than 10MΩ. For most input ranges, the input voltage can swing to 25V or -25V without damage to the converter.AnSPI-compatible serial interface allows data to be synchronized to an internal or external clock. The ADS8513 is specified at 40kSPS sampling rate over the industrial -40°C to +85°C temperature range.特性40kSPS Min SamplingRateVery Low Power: 24mW Typ±3.33V, ±5V, ±10V, 4V, and 10V Input Ranges89dB SNR with 10kHz Input±2LSB Max INL-1/+2LSB Max DNL, 16-Bit NMC±10mV BPZ, ±2.5ppm/°C BPZ Drift89dB Min SINAD, 102dB Min SFDRUses Internal or External 2.5-V ReferenceNo External Calibration Resistors RequiredSingle 5V Analog Supply32.5W Max Power Dissipation 50µW Max Power-Down ModeSPI™-Compatible Serial Port up to 20MHz Master/Slave FeatureGlobal CONV and 3-Stated Bus for Multi-Chip Simultaneous S/H OperationPin-Compatible With 16-Bit ADS7813 and 12-Bit ADS7812 and ADS8512SO-16 PackageAPPLICATIONSIndustrial Process ControlTest EquipmentRoboticsDSP Servo ControlMedical InstrumentationPortable Data Acquisition SystemsQSPI, SPI are trademarks of Motorola, Inc.
