MAX35104 Gas Flow Meter SoC
Analog Devices MAX35104 Gas Flow Meter SoC is targeted as an analog front-end solution for the ultrasonic gas meter and medical ventilator markets. With a time measurement accuracy of 700ps and automatic differential Time-of-Flight (ToF), the Analog Devices MAX35104 makes for simplified computation of gaseous flow. The power consumption is the lowest available with ultra-low 62µA ToF measurement and 125nA duty-cycled temperature measurement. Multi-hit (up to six per wave) capability with stop-enable windowing allows the device to be fine-tuned for the application. Internal analog switches, a configurable three-stage integrated operational amplifier chain amplifier, and an ultra-low input offset comparator provide the analog interface and control for a minimal electrical bill of material solution.
