AWM2100V

The AWM2100V is a Microbridge Mass Airflow Sensor, passive device comprised of two Wheatstone bridges. The heater control circuit is required for operation per specifications. The sensing bridge supply circuit is also required for operation per specifications. The differential amplifier is an useful interface for the sensing bridge. It can be used to introduce gain and to voltage offsets to the sensor output.
