HBP411 Pressure Sensor Series
The HBP411 product series are piezoresistive MEMS pressure sensors. Utilizing a Wheatstone bridge structure on a circular silicon diaphragm, these sensors offer high sensitivity, stability, and linearity. They are designed for use with non-corrosive gases or liquids and are available in standard DIP6 packages for ease of use. The sensors provide a linear voltage output signal proportional to the applied pressure. Customers can integrate standard amplification circuits, such as instrumentation amplifiers, for signal conditioning, debugging, and compensation to achieve high-precision, stable, and reliable pressure measurements.

Pin Definitions
Refer to the provided diagrams for specific pinout configurations (Straight Plug and Reverse Plug).
Reference Circuit
Instrumentation amplifiers are recommended for amplifying the sensor's weak signals due to their differential input, single-ended output, high input impedance, and high common-mode rejection ratio.
