An NMOS operational amplifier suitable for a buffer of analog LSI's is reported. It contains three gain stages to achieve the overall gain of 70 db and a buffer stage of drive a capacitance of 200 pf. A monolithic NMOS 10-bit D/A converter including this amplifier as an output buffer has exhibited 10-bit absolute linearity.
