The OPA134PAG4 is a SoundPlus high performance audio operational amplifier in 8 pin DIP package. It is an ultra low distortion, low noise operational amplifier. A true FET input stage was incorporated to provide superior sound quality and speed for exceptional audio performance. This in combination with high output drive capability and excellent DC performance allows use in a wide variety of demanding applications. The OPA134 is easy to use and free from phase inversion and overload problems often found in common FET input op amps. This device is unity gain stable and provides excellent dynamic behaviour over a wide range of load conditions including high load capacitance.
