描述The ADS8383 is an 18-bit, 500 kHz A/D converter. The device includes a 18-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8383 offers a full 18-bit interface, a 16-bit option where data is read using two read cycles or even an 8-bit bus using three read cycles. The ADS8383 is available in a 48-lead TQFP package and is characterized over the industrial ?40°C to 85°C temperature range.特性500-kHz Sample Rate 18-Bit NMC Ensured Over Temperature Zero Latency Low Power: 110 mW at 500 kHz Unipolar Input Range Onboard Reference Buffer High-Speed Parallel Interface Wide Digital Supply 8-/16-/18-Bit Bus Transfer 48-Pin TQFP Package APPLICATIONS Medical Instruments Optical Networking Transducer Interface High Accuracy Data Acquisition Systems Magnetometers
