Integrated circuit device, electro-optical device, and electronic instrument

An integrated circuit device comprising:

• first to Nth (N is an integer equal to or larger than two) memory blocks that are disposed along a first direction and store image data;
• a power supply circuit that generates a power supply voltage;
• and
• a data driver that is disposed along the first direction and spaced from the first to Nth memory blocks in a second direction, the second direction being perpendicular to the first direction and supplying data signals to a plurality of data lines of an electro-optical device,
• the power supply circuit including an analog reference power supply voltage output circuit that outputs an analog reference power supply voltage;
• the analog reference power supply voltage output circuit being disposed between an Mth (M is a natural number) memory block and an (M+1)th memory block among the first to Nth memory blocks;
• and
• an analog reference power supply line that supplies the analog reference power supply voltage being provided in an area of the data driver along the first direction,
• the analog reference power supply voltage being supplied to a second input terminal of an operational amplifier that is included in a sample-hold circuit included in the data driver and has a first input terminal and the second input terminal.
