简  介:a FEATURES Excellent Sonic Characteristics Low Noise: 6 nV/√Hz Low Distortion: 0.0006% High Slew Rate: 22 V/ s Wide Bandwidth: 9 MHz Low Supply Current: 5 mA Low Offset Voltage: 1 mV Low Offset Current: 2 nA Unity Gain Stable SOIC-8 Package APPLICATIONS High Performance Audio Active Filters Fast Amplifiers Integrators GENERAL DESCRIPTION OUT A 1 –IN A 2 +IN A 3 V– 4 Dual Bipolar/JFET, Audio Operational Amplifier OP275* PIN CONNECTIONS 8-Lead Narrow-Body SO (S Suffix) 8 8-Lead Epoxy DIP (P Suffix) V+ OUT B –IN B +IN B OUT A –IN A +IN A V– 1 2 3 4 OP275 8 7 6 5 V+ OUT B –IN B +IN B OP275 7 6 5 The OP275 is the first amplifier to feature 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 6 Hz maintains a flat noise density response. Whether noise is measured at either 30 Hz or 1 kHz, it is only 6 nV/√Hz. 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 22 V/s 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 5 mA of supply current, lower than any standard ……
