GENERAL DESCRIPTION  
Improved dc performance is also provided with bias and offset  
currents greatly reduced over purely bipolar designs. Input offset  
voltage is guaranteed at 1 mV and is typically less than 200 µV.  
This allows the OP275 to be used in many dc-coupled or sum-  
ming applications without the need for special selections or the  
added noise of additional offset adjustment circuitry.  
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.  
The output is capable of driving 600 loads to 10V rms while  
maintaining low distortion.THD + Noise at 3V rms is a low  
0.0006%.  
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,  
The OP275 is specified over the extended industrial (–40°C to  
+85°C) temperature range. OP275s are available in both plas-  
tic DIP and SOIC-8 packages. SOIC-8 packages are available  
in 2500-piece reels. Many audio amplifiers are not offered  
in SOIC-8 surface-mount packages for a variety of reasons;  
however, the OP275 was designed so that it would offer full  
performance in surface-mount packaging.  
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 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  
5 mA of supply current, lower than any standard audio amplifier.
