SCC SMT Series
The SCC series sensors offer an extremely low cost sensor element with a
temperature stable output when driven with a constant current source.
These integrated circuit sensors were designed for extremely cost sensitive
applications where precise accuracy over a wide temperature range is not
required.
The SCC series SMT offers a standard surface mount package and is
offered with an optional ported lid to fit in a variety of application. This series
of sensors are designed for measuring absolute and gage pressure ranges
from 0 psi to 5 psi through 0 psi to 300 psi. The absolute devices have an
internal vacuum reference and an output voltage proportional to absolute
pressure. Differential devices allow application of pressure to either side of
the sensing diaphragm and can be used for gauge or differential
measurements.
The SCC series SMT sensors offer a 4-pin closed bridge configuration for
electrical connection with additional pads provided for mechanical support.
Pulsed power is recommended to achieve maximum accuracy and conserve
battery power in portable applications.

A
= 25 °C to 70 °C [32 °F to 158 °F],
Common-mode Line Pressure = 0 psig, Pressure Applied to P1 unless otherwise noted.
If the maximum pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing
die may fracture.
Sensitivity is the ratio of the output signal voltage change to the corresponding input pressure change. The
sensitivity is characterized by design and periodic production testing. This parameter in not 100 % tested in
production.
Linearity is based on best straight line fit. Hysteresis is the maximum output difference at any point within the
operating pressure range for increasing and decreasing pressure.
Maximum error band of the offset voltage and the error of the band of the span over the compensated
temperature range, relative to the 25 °C reading. Typical temperature coefficients for span and resistance are
-2200
ppm/°C and 2200 ppm/°C respectively. Temperature effects on offset and span are guaranteed by design.
These parameters are not 100 % tested in production.
Long term stability over a one year period.
Response time for 0 psi to full scale span pressure step change.
