The OPA2134 is a ultra-low distortion, low noise operational amplifiers fully specified for audio applications. A true FET input stage was incorporated to provide superior sound quality and speed for exceptional audio performance. This in combination with a high output drive capability and excellent dc performance allows use in a wide variety of demanding applications. In addition the OPA2134's wide output swing, to within 1V of the rails, allows increased headroom making it ideal for use in any audio circuit. OPA2134 op amps are easy to use and free from phase inversion and overload problems often found in common FET input op amps.
