MAX35102ETJ+ by Analog Devices

Time-to-Digital Converter Without RTC


The MAX35102 is a time-to-digital converter with built-in amplifier and comparator targeted as a low-cost, analog front-end solution for the ultrasonic heat meter and flow meter markets. It is similar to the MAX35101, but with a reduced feature set and without a real-time clock (RTC). The package size has been reduced to 4mm x 4mm x 0.75mm with 0.4mm pin pitch. 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.
