OP275GSZ Datasheet PDF - ADI

●The OP275GSZ is a Dual Bipolar/JFET Audio Operational Amplifier features the Butler Amplifier front end. This new front end design combines both bipolar and JFET transistors 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 that of previous audio amplifiers, but at much lower supply currents. A very low l/f corner of below 6Hz maintains a flat noise density response. The JFET portion of the input stage gives the OP275 its high slew rates to keep distortion low, even when large output swings are required and the 22V/µs slew rate of the OP275 is the fastest of any standard audio amplifier. Best of all, this low noise and high speed are accomplished using less than 5mA of supply current, lower than any standard audio amplifier. Improved DC performance is also provided with bias and offset currents greatly reduced over purely bipolar designs.
