Abstract: Aspects of this disclosure relate to compensating for a relatively large offset in a signal generated by a sensor, such as a pressure sensor and/or a resistive bridge based sensor. Such offset compensation can include applying an offset correction signal generated by a configurable voltage reference, such as a voltage mode digital-to-analog converter (DAC), to an input of an amplifier included in an instrumentation amplifier to compensate for the offset of the signal generated by the sensor.
