Product Summary

The OP275G is a dual bipolar/JFET, audio operational amplifier. The OP275G is the first amplifier to feature the Butler Amplifier front-end. This new front-end design combines both bipolar and JFET transistors of the OP275G to attain amplifiers with the accuracy and low noise performance of bipolar transistors, and the speed and sound quality of JFETs. Total Harmonic Distortion plus Noise equals of the OP275G that of previous audio amplifiers, but at much lower supply currents.
