[Outline]
This product is a Gage pressure sensor which MEMS*1 Gage pressure sensor and AFE IC*2 are modularized. It digitally outputs a pressure value which was corrected in the module.
Customers need no correction because it corrects and outputs the differences of sensors and temperature characteristics. It does not require complicated sensor drive or control circuit, and devices with high performance can be made only with this module and an external microcontroller which will be the host.
*1 MEMS
: [Micro-Electro-Mechanical Systems]
*2 AFE IC
: [Analog Front End IC]
