High-Speed Analog-to-Digital Converters

  • Three 12-bit Resolution SAR ADCs
  • Up to 40 Msps Conversion Rate per ADC
  • Up to 14 Analog Input Pins
  • 16-bit Sampling Capability
  • Sixteen Settings Channels. Each Channel:
    • Can be assigned to any analog input (I/O pin or internal signal)
    • Can be set to a different sampling time
    • Can be configured as single-ended or differential
    • Conversion result can be formatted as unsigned or signed
    • Conversion result can be left-aligned (fraction format)
    • Has a separate 32-bit conversion result register
  • Supports Four Sampling Modes:
    • Oversampling of multiple samples
    • Integration of multiple samples
    • Window (multiple samples accumulated when the gate signal is active)
    • Single conversion
    • All channels have a digital comparator to detect configurable thresholds
    • The last three setting channels have the second result accumulator to implement second-order filters
