Patent ID: 8754796

Claim:
A semiconductor device comprising: a driver circuit comprising: a first latch circuit; a second latch circuit; a third latch circuit; a fourth latch circuit; a first D/A conversion circuit; a second D/A conversion circuit; and a buffer circuit, wherein the first latch circuit, the second latch circuit, the first D/A conversion circuit and the second D/A conversion circuit are connected in series, wherein the third latch circuit, the fourth latch circuit and the second D/A conversion circuit are connected in series, wherein the second D/A conversion circuit is a resistor string D/A conversion circuit, wherein the first D/A conversion circuit is configured to output a first voltage and a second voltage and to supply the first voltage and the second voltage to the second D/A conversion circuit, wherein the second D/A conversion circuit is configured to output a third voltage to the buffer circuit, and wherein the driver circuit is configured to output the first voltage to the buffer circuit just before the third voltage is outputted to the buffer circuit.
