MAX35103EHJ+ by Analog Devices

Reduced Power Time-to-Digital Converter with AFE, RTC, and Flash


The MAX35103 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 consumes about half the average power and increases the maximum ToF measurement frequency in event timing mode from 2Hz to 16Hz. With a time measurement accuracy of 20ps and automatic differential time-of-flight (ToF) measurement, this device makes for simplified computation of liquid flow. Average power consumption is the lowest available with ultra-low 5.5μA ToF measurement and < 125nA duty-cycled temperature measurement.
