Home / Products / Sensor Interfaces / PICOCAP Capacitive Sensing / PCAP02 Capacitance-to-Digital Converter

Features

  • Wide input range (fF to nF)
  • Low noise (15 aF RMS)
  • High update rate up to 500kHz
  • Low current consumption down to 2µA
  • Internal signal processor

Benefits

  • Enables platform designs (one part – different configurations)
  • Enables compact designs due to internal signal processor
  • Allows for low power designs, e.g. wireless applications
  • Enables mutli-channel designs (up to 8 sensors)
