AWM2100V产品概述
The AWM2000 Series microbridge mass airflow sensor is a passive device comprised of two Wheatstone bridges. The heater control circuit is required for operation per specifications. The sensing bridge supply circuit-in is also required for operation per specifications. These two circuits are not on board the package and must be supplied in the application. The differential amplifier is a useful interface for the sensing bridge. It can be used to introduce the gain and to introduce voltage offsets to the sensor output. The AWM3000 Series is amplified; therefore, it can be used to increase the gain and to introduce voltage offsets to the sensor output. The AWM3000 Series is ideal for ultra-low flow applications. Also, the heater control circuit and the sensing bridge supply circuit are on board the AWM3000 package. Features:
