Product Summary
The OP275 is a dual bipolar/JFET, audio operational amplifier. This new front-end design combines both bipolar and JFET transistors of the OP275 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 OP275 that of previous audio amplifiers, but at much lower supply currents. Applications include High Performance Audio, Active Filters, Fast Amplifiers, Integrators.
