1. A driver comprising:
a first driving circuit configured to supply a data signal to a signal supply line of an electrooptic panel based on gradation data; and
a second driving circuit including a computation amplifier, an output capacitor, a first feedback capacitor, and a second feedback capacitor, and electrically coupled to the signal supply line, the computation amplifier being made up of a transistor with a breakdown voltage lower than a breakdown voltage of a transistor making up the first driving circuit, the output capacitor being disposed between an output node of the computation amplifier and the signal supply line, the first feedback capacitor being disposed between an inverting input node of the computation amplifier and the signal supply line, the second feedback capacitor including one end electrically coupled to the inverting input node of the computation amplifier.
