CAM312

The CAM312 is the newest and most cost effective processor IC for resonant inductive position sensing. It can connect to and process up to two sensors and reports results over an SPI interface.

Development boards are available for evaluation, prototyping and development of CAM312 based solutions. Find out more here

 

Features

  • Resonant inductive position sensing engine
  • Fully ratiometric measurements
  • Fast SPI communications (slave device)
  • User IOs for sample indicators
  • Measures two Type 4 or 1 sensors or one Type 2, 3 or 6
  • SPI interface checksum available for integrity check
  • Analog output possible using an external DAC
  • Power down mode for reduced supply current
  • Internal software upgradable over SPI

Performance

  • Maximum update rate 2000 independent samples per second
  • Group Delay from physical position to SPI ready 200µs
  • Noise Free Resolution 10…15 bits at typical gap, depending on sensor
  • Automatic tuning to resonators across ±10% frequency range
  • Single 3.0...3.6V supply
  • -40°C to +125°C (CAM312ME)
  • -40°C to +150°C available
