High-Speed Analog-to-Digital Converters

  • Five 12-Bit Resolution ADCs
  • Up to 40 MSPS
  • Up to 26 Analog Input Pins
  • 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 settings channels have the second result accumulator to implement second order filters.
  • Band Gap Reference and Temperature Sensor Diode Inputs
