An input terminal of the operational amplifier integrator is coupled to a touch sensor. When the circuit is operated under a display driving mode, an input terminal of the unity gain buffer amplifier receives a gray level voltage and an output terminal of the unity gain buffer amplifier is coupled to a display panel. When the circuit is operated under a fingerprint detecting mode, the input terminal and the output terminal of the unity gain buffer amplifier are respectively coupled to a fingerprint sensor and the ADC circuit.
