Some other good examples of applications that will benefit from the INA333 are weigh scales or bridge sensor systems. In a bridge sensor system, normally full scale output voltages are in the 10 mV to 100 mV range or 2mV per volt of excitation. These voltages need to be amplified for the data acquisition system. The key role of the instrumentation amplifier is to amplify the very small differential input voltage and reject the common-mode input voltage. For the best performance, the instrumentation amplifier must have excellent long term stability with regard to offset drift and gain because real world sensors have span and offset errors that are ever changing over temperature. Also, many bridge pressure sensors have a nonlinear output with applied force and the accuracy of the amplified input signal must be guaranteed over years of operation. A zero drift instrumentation amplifier such as the INA333 easily meets these stringent requirements by achieving an offset drift of 0.05µV/°C.
