SM5651, 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 SM5652, a constant voltage supply can be used and the normalized output span of each sensor can then be easily amplified.The model SM5651 is designed for constant current excitation.The model SM5652 is designed for constant voltage excitation.Various electrical pin and pressure port configurations are available for flexibility in matching this product to specific applications.
