Time-to-digital converter ultrasonic flow metering applications

20-04-2015 | Mouser Electronics | Test & Measurement

Suitable for gas, water and heat ultrasonic metering applications, Maxim's
MAX35102 time-to-digital converter is now stocked by Mouser.

The device includes a built-in amplifier and comparator and is aimed at
low-cost, analog front-end (AFE) solution for the ultrasonic flowmeter
markets. The device is similar to the MAX35101, but with a reduced feature
set, and it does not include a real-time clock (RTC). With a time
measurement accuracy of 20ps and automatic differential time-of-flight (ToF)
measurement, this device makes for simplified computation of liquid flow.
Power consumption is the lowest available with ultra-low 5.5µA ToF
measurement and <125nA duty-cycled temperature measurement, says the
company.
