    产品信息

    描述The ADS8482 is an 18-bit, 1-MSPS A/C converter with an internal 4.096-V reference and a pseudo-bipolar, fully differential input. The device includes a 18-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8482 offers a full 18-bit interface, a 16-bit option where data is read using two read cycles, or an 8-bit bus option using three read cycles. The ADS8482 is available in a 48-lead 7x7 QFN package and is characterized over the industrial -40°C to 85°C temperature range.特性0 to 1-MHz Sample Rate±1.2 LSB Typ, ±2.5 LSB Max INL+0.75/-0.6 LSB Typ, +1.5/-1 LSB Max DNL18-Bit NMC Ensured Over Temperature±0.05-mV Offset Error±0.05-PPM/°C Offset Error Drift±0.035 %FSR Gain Error±0.5-PPM/°C Gain Error Drift99dB SNR, -121db THD, 123dB SFDRZero LatencyLow Power: 225 mW at 1 MSPSUnipolar Differential Input Range: Vref to -VrefOnboard Reference with 6 PPM/°C DriftOnboard Reference BufferHigh-Speed Parallel InterfaceWide Digital Supply 2.7 V to5.25 V8-/16-/18-Bit Bus Transfer48-Pin 7x7 QFN PackageAPPLICATIONSMedical InstrumentsOptical NetworkingTransducer InterfaceHigh Accuracy Data Acquisition SystemsMagnetometers
