Signal/Power Technology

Low-cost Time of Flight Measurement for Ultrasonic Meters

  • Low-noise op amps
  • Combine with CTMU on PIC® MCU to achieve time of flight measurement down to 200pS resolution
  • Eliminates need for time measurement ASIC used in ultrasonic flow measurement

Extend Battery Life with low quiescent current and operating voltage

  • Op-amps down to 450nA with operation down to 1.4v
  • Linear regulators to 1.6uA with
  • Temperature sensors down to 2.3v

Fewer External Components Lower System Costs

  • LDO’s with preset voltages eliminate external components
  • Reduced design complexity
