Overview
The MPXV7025DPT1 is a state-of-the-art monolithic silicon pressure sensor produced by Freescale Semiconductor, now part of NXP. This piezoresistive transducer is designed for a wide range of applications, particularly those that utilize microcontrollers or microprocessors with A/D inputs. The sensor combines advanced micromachining techniques, thin-film metallization, and bipolar processing to provide an accurate, high-level analog output signal that is proportional to the applied pressure.
