CAM204

CAM204 chip with markings enhanced for clarityThe CAM204 is a single-chip non-contact position sensor IC for resonant inductive position sensing.  It can connect to and process multiple sensors and report results to a host over a single SPI interface.


Features

  • Resonant inductive position sensing engine
  • Fully ratiometric measurements
  • SPI communications (slave device)
  • User IOs for position triggers and sample indicators
  • Can process multiple sensors for centralised processing...
    • Up to 4 Type 1 sensors
    • Up to 2 Type 6 sensors
  • Can drive external DAC for up to 4 analog outputs
  • Internal software upgradable over SPI

Performance

  • Noise Free Resolution 10…16 bits at typical gap, depending on sensor
  • Automatic tuning to resonators across ±7% frequency range
  • Extremely stable across temperature...
    • < ±0.1% position change across temperature for Type 1 sensors
    • < ±0.01% for Type 2 and 6
  • Update rate > 1000 samples/s
  • Single 2.7...3.6V supply
  • -40°C to +125°C 28-pin SSOP (CAM204BE)
  • -40°C to +85°C 28-pin QFN (CAM204MI)
