[Outline]
This product is an altitude atmospheric pressure sensor which MEMS absolute pressure sensor and AFE IC are modularized. It digitally outputs a pressure value which was corrected completely in the module.
Customers need no correction at all 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.

[Features]   (Unless otherwise specified, Topr=+25C)
1. Small package :
3.0(W)3.0(D)1.1(H) mm
2. It is able to measure atmospheric pressure from the altitudes of 0m to 9000m equivalent.
(from 30kPa to 110kPa)
3. It has Performs high resolution of max 2.0Pa. (0.17m)
4. It corrects the diff erences of sensors and temperature characteristics when shipped from our factory.
5. It digitally outputs a corrected pressure value by a built-in sequencer. (SPI, I2C)
