The application report tells you information about sampling, bridge output, sensitivity, bridge, operational amplifier, offset voltage, power, output signal, bridge sensitivity, adc, conditioning, calculation, amplifier, sensor, and pressure sensor. Inside this application report we can find information regarding power signal, compensation, reference, amplifier gain, error, offset, calibration, linear approximation, signal conditioning, output voltage, approximation, amplifier stage, range, filter, and circuit.

Lots of things such as cutoff frequency, bridge supply, supply voltage, power consumption, measurement, reference voltage, design, pressure variation, sensor output, signal, accuracy, power supply, voltage, current, and minimum sensitivity are described in this application report. The following are some excerpt from the application report:

Basics Signal conditioning in today’s applications typically consists of a circuit to connect an analog sensor to a digital acquisition system. This circuit requires three functions: the first one to linearize the output signal of the sensor, the second to amplify the signal to a degree that it falls within the ADC input range, and the third to limit the signal frequency such that it does not exceed the capabilities of the digital system that follows (see Figure 2–1).

Even more, the application report presents info about offset calibration, pressure, digital processing, output, errors, function, solution, pressure sensors, error compensation, resolution, amplifier output, atmospheric pressure, maximum sensitivity, gain adjustment, and gain.
