GENERAL DESCRIPTION
The OP176 is a low noise, high output drive op amp that
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 previous audio
amplifiers, but at much lower supply currents.
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
*Protected by U.S. Patent No. 5101126.

200 µV. This allows the OP176 to be used in many dc coupled
or summing applications without the need for special selections
or the added noise of additional offset adjustment circuitry.
The output is capable of driving 600 Ω loads to 10 V rms while
maintaining low distortion. THD + Noise at 3 V rms is a low
0.0006%.
The OP176 is specified over the extended industrial (–40°C to
+85°C) temperature range. OP176s are available in both plastic
DIP and SO-8 packages. SO-8 packages are available in 2500
piece reels. Many audio amplifiers are not offered in SO-8
surface mount packages for a variety of reasons, however, the
OP176 was designed so that it would offer full performance in
surface mount packaging.
