MCP-H21 Digital signal sensor

Descriptions
The MCP-H21 series is a small-sized package (SOP) with dual ports, which integrates signal amplification, nonlinearity, and temperature compensation for silicon piezoresistive differential pressure sensors. The MCP-H21 series pressure sensor is a product designed specifically for consumer electronics and medical applications using advanced MEMS technology. The pressure sensor can be directly soldered onto a PCB board, providing a linear and high-precision 24-bit digital pressure signal and a 16-bit digital temperature signal.

1. The high-pressure side is on the marked side.
2. The maximum deviation from a best fit straight line (BFSL) fitted to the output measured over the pressure range at 25C. Includes all errors due to pressure non-linearity, hysteresis, and non-repeatability.
3. Total pressure error band includes all accuracy errors, thermal errors over the compensated temperature range and span and offset calibration tolerances. For ideal sensor output with respect to input pressure and temperature, TEB values are valid only at the calibrated supply voltage.
