acam - Solutions in Time

Time - the most universal of all physical quantities -  offers fantastic possibilities to solve difficult measurement tasks elegantly. Nearly all physical units like position, weight, pressure and temperature can be captured by time measurement.


Based on digital TDC-technology (TDC = Time -to-Digital Converter), acam's products transfer the manifold potential of precise time measurement to consumer, automotive, industry and scientific applications and offer professional solutions for difficult measurement tasks.


GP30 - The next generation SoC for ultrasonic flow meters




GP30 is the next generation in acam’s development for ultrasonic flow converters.





  • Easy-to-adapt two-chip solution for ultrasonic heat, water and gas meters (GP30 + simple µP)
  • Single-chip solution for many industrial applications or pure flow meter parts
  • All flow and temperature calculations are done by GP30
  • MID compliance without external µP
  • External µP for interfaces (e.g. LCD, wireless, etc.) and other general-purpose tasks
  • Enables use of the same external µP and software for mechanical and ultrasonic heat and water meters
  • ultra low power 32-Bit µP (77 µA/MHz)

PICOCAP Capacitance-to-Digital Converters

acam's PICOCAP product line of capacitance-to-digital converters convinces in many aspects - resolution (up to 18 bit or 23 aF rms@ 10pF), low power (low as a 2 µA operating), speed (up to 500 kHz), flexible capacitance range from 1 pF to 100 nF, and many more.

On top of that, a number of new features have been added, e.g. the internal reference capacitance to save external components or the newly added EEPROM for storing user calibration data. Further, improvements for the operation with humidity and MEMS sensors have been made.
