Abstract: An integrated circuit and a touch display apparatus are provided. The integrated circuit is configured to drive a touch display panel. The integrated circuit includes a regulator. An output terminal of the regulator is employed as a first node to output a common voltage, wherein the common voltage is configured to be provided to at least one common electrode of the touch display panel. An input terminal of the regulator is coupled to a second node different from the first node to receive a feedback voltage.
