OPA2134PA

OPA2134PA is an OPA134 series dual SoundPlus™ high performance audio operational amplifier. It is fully specified for audio applications. A true FET input stage is incorporated to provide superior sound quality and speed for exceptional audio performance. This combined with high output drive capability and excellent DC performance, allows for use in various demanding applications. In addition, it has a wide output swing within 1V of the rails, allowing increased headroom and making it ideal for use in any audio circuit. It is easy to use and free from phase inversion and the overload problems often found in common FET-input operational amplifier. Input cascade circuitry provides excellent common line driver mode rejection and maintains low input bias current over its wide input voltage range, minimizing distortion. Application includes professional audio and music, line drivers, line receivers, multimedia audio, active filters, preamplifiers, integrators, crossover networks.
