描述The ADS8412 is a 16-bit, 2 MHz A/D converter with an internal 4.096-V reference. The device includes a 16-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8412 offers a full 16-bit interface and an 8-bit option where data is read using two 8-bit read cycles.The ADS8412 has a unipolar differential input. It is available in a 48-lead TQFP package and is characterized over the industrial –40°C to 85°C temperature range.特性2-MHz Sample Rate 16-Bit NMC Ensured Over Temperature Zero Latency Unipolar Differential Input Range: Vref to –Vref Onboard Reference Onboard Reference Buffer High-Speed Parallel Interface Power Dissipation: 175 mW at 2 MHz Typ Wide Digital Supply 8-/16-Bit Bus Transfer 48-Pin TQFP Package ESD Sensitive – HBM Capability of 500 V, 1000 V at All Input Pins APPLICATIONS DWDM Instrumentation High-Speed, High-Resolution, Zero Latency Data Acquisition Systems Transducer Interface Medical Instruments Communication
