Single chip, eight-channel 16-bit ADC

Your current ADC will be downed by a high voltage noise on its inputs! Not OctAD-16! It can withstand up to 150 V…

  • No need any longer for expensive instrumentation amplifiers between sensor and converter
  • Cost saving and reliability increase while converting analog signals from DISTANT sensors:
    • concentration of analog signals for conversion on single board
    • low sensitivity to noise, while keeping the sensor at a distance
    • low maintenance hassle of your data conversion module
  • Benefits today from electronics embedded in the airplane of tomorrow!

Features

  • same interface for distant or local sensors
  • Single +3.3 V power supply ± 10 %
  • Temperature range from -40 °C to 85 °C
  • Main clock: 256 Fs
  • Cascadable chip
  • JTAG port
  • PQFP 100 package

Key characteristics

  • Large Common Mode Input Voltage Range: ± 10 V for using remote sensors (several tens of meters)
  • High Common Mode Rejection Ratio (CMRR): 60 dB for filtering parasitics on analog signal
  • Typical SNR 85 dB in the band (10 Hz, Fs/2)
  • Useful signal in the band (DC, Fs/8)
  • Output sampling Fs between 2 kHz and 16 kHz
  • Typical power consumption < 100 mA

Main applications
