Overview
The MPXV7025DP, produced by Freescale Semiconductor (now part of NXP Semiconductors), is a state-of-the-art monolithic silicon pressure sensor. This piezoresistive transducer is designed in a small outline package (SOP) and is suitable for a wide range of applications, particularly those involving 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 proportional to the applied pressure.
