描述The ADS8517 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 device. AnSPI-compatible serial interface allows data to be synchronized to an internal or external clock. A full parallel interface using the selectable BYTE pin is also provided to allow the maximum system design flexibility. The ADS8517 is specified at a 200-kHz sampling rate over the industrial -40°C to +85°C temperature range.特性200-kHz Minimum Sampling Rate 4-V, 5-V, and ±10-V Input Ranges with High-Impedance Input ±1.5 LSB Max INL +1.5/-1 LSB Max/Min DNL, 16 Bits NMC ±2-mV Max BPZ, ±0.6 ppm/°C BPZ Drift ±2-mV Max UPZ, ±0.15 ppm/°C UPZ Drift 88.8-dB SINAD with 10-kHz Input SPI-Compatible Serial Output With Daisy-Chain (TAG), SPI Master/Slave Feature Full Parallel Interface Binary Twos Complement or Straight Binary Output Code Formats Single 4.5-V to 5.5-V Analog Supply, 1.65-V to5.5-V Interface Supply Uses Internal 2.5-V or External Reference No External Precision Resistors Required Low Power Dissipation (ADC+REF+BUF): 47 mW Typ, 60 mW Max at 200 kSPS 50-µW Max Power-Down Mode Pin-Compatible with 16-Bit ADS7807 and ADS8507, and 12-Bit ADS7806 and ADS8506 SO-28 and TSSOP-28 Packages APPLICATIONS Portable Test Equipment USB Data Acquisition Module Medical Equipment Industrial Process Control Digital Signal Processing InstrumentationAll trademarks are the property of their respective owners.
