MCP-J10, MCP-J11, MCP-J12 Pressure sensor for automobiles

Product Overview

The MCP-J10 series is a calibrated absolute pressure sensor for air pressure measuring. The product uses an automotive-grade signal conditioning chip to calibrate and compensate the MEMS output signal, converting pressure signals from 10kPa to 1500kPa into analog output signals (0 to 5V). While ensuring the excellent reliability of the product, the two chips are integrated into the package, greatly reducing the package size. At the same time, the conditioned product provides standard output over the range of temperature and accuracy.

Product Description

The MCP-J11 series is a calibrated absolute pressure sensor product. This product uses automotive-grade signal conditioning chips to calibrate and compensate for MEMS core output, and can convert pressure signals from 10kPa to 1500kPa into digital IIC output signals. While ensuring the excellent reliability of the product, the two chips are integrated and packaged, greatly reducing the packaging size. At the same time, the conditioned product can provide standard output within the temperature range and accuracy range, eliminating the need for customers to calibrate the sensor.
