SILICON MICROSTRUCTURES INCORPORATED • SM5611/SM5612 OEM Pressure, Constant Current DIP OEM Pressure, Constant Voltage DIP OEM PRESSURE TRANSDUCER FULLY TEMPERATURE COMPENSATED AND CALIBRATED DUAL-IN-LINE PACKAGE DESCRIPTION The SM5600 Series of OEM pressure sensors are fully calibrated, temperature compensated pressure sensors in dual inline packages for printed circuit board mounting. These sensors offer improved performance as well as the option for either constant current or constant voltage excitation. Ultra-low pressure ranges are also available (see SM5651/SM5652 datasheet), resulting in the broadest selection of standard pressure ranges in the industry. The SM5600 Series pressure sensors are constructed by attaching a highly stable piezoresistive pressure sensor chip to a ceramic substrate. Thick film resistors on the ceramic are laser trimmed during manufacturing to provide zero offset calibration, temperature compensation for zero offset, and temperature compensation for sensitivity. In the Model SM5611, an additional resistor is trimmed to normalize the output of an external differential amplifier to provide span calibration when the sensor is driven by a constant current supply. In the Model SM5612, a constant voltage supply can be used and the normalized output span of each sensor can then be easily amplified.
