A driver includes a first driving circuit and a second driving circuit. The second driving circuit includes a computation amplifier, an output capacitor, a first feedback capacitor, and a second feedback capacitor. The computation amplifier is composed of a transistor with a breakdown voltage lower than the breakdown voltage of a transistor making up the first driving circuit. The output capacitor is disposed between an output node of the computation amplifier and the signal supply line. The first feedback capacitor is disposed between an inverting input node of the computation amplifier and the signal supply line. One end of the second feedback capacitor is coupled to the inverting input node of the computation amplifier.

Driver, electrooptical device and electronic apparatus

An integrated circuit device includes first to Nth memory blocks disposed along a first direction, a power supply circuit, and a data driver disposed in a second direction with respect to the first to Nth memory blocks. The power supply circuit includes an analog reference power supply voltage output circuit that outputs an analog reference power supply voltage. The analog reference power supply voltage output circuit is disposed between an Mth memory block and an (M+1)th memory block among the first to Nth memory blocks. An analog reference power supply line is provided in an area of the data driver along the first direction.
