SIGNAL CONDITIONING CIRCUIT AND PEDAL SIGNAL DETECTION CIRCUIT

The present invention relates to the technical field of electronic circuits, and specifically provides a signal conditioning circuit and a pedal signal detection circuit, aiming at solving the problem of how to convert an analog signal to adapt to an ADC having a relatively small input voltage range. To achieve this objective, the signal conditioning circuit of the present invention comprises: a power supply circuit and at least one acquisition circuit; the power supply circuit is provided with a first operational amplification unit used for converting a reference voltage into a target voltage and a voltage follow-up unit used for providing the target voltage to a load; and the acquisition circuit comprises a second operational amplification unit used for converting the target voltage and a sampling voltage acquired from the load to be within a preset input voltage range. On one hand, the power supply requirement of the load and the preset input voltage range of the ADC can be met at the same time; and on the
