OPA134UA

The OPA134UA is a SoundPlus™ high performance audio Operational Amplifier, a true FET input stage is incorporated to provide superior sound quality and speed for exceptional audio performance. This amplifier has a wide output swing, to within 1V of the rails, allowing increased headroom and making it ideal for use in any audio circuit. The OPA134 SoundPlus™ audio operational amplifier is easy to use and free from phase-inversion and the overload problems often found in common FET-input operational amplifiers. Input cascode circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range, minimizing distortion. This operational amplifier is unity-gain stable and provide excellent dynamic behaviour over a wide range of load conditions, including high load capacitance. The dual and quad versions feature completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded.
