Gage and Absolute
Temperature Compensated
DESCRIPTION
The MS4426 is a temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-
in- line configuration and intended for cost sensitive applications where excellent performance and long-term
stability are required.
Integral temperature compensation is provided over a range of 0-50°C using laser-trimmed resistors.
The pressure sensor is available in absolute or gage pressure ranges from 0-1 to 0-300 psi. The pressure ports
are 1/8” barbed ports which mate with 3/32” ID tubing. The tube is vertically mounted to the printed circuit board.
For a horizontally mounted tube in differential, gage and absolute pressure, refer to the MS4425.

Notes
1. Ratiometric to supply voltage.
2. Best fit straight line. Non linearity for 5psi and 150psi devices is 0.25%
3. Maximum temperature error between 0°C and 50°C with respect to 25°C. For errors beyond the compensated temperature, see
Temperature Error Multiplier Chart below.
4. Long term stability over a one year period with constant voltage and temperature.
5. 3X or 400 psi max, whichever is less.
6. For more details refer to 4425/4426 Mounting Application Note.
