The OPA134, OPA2134, and OPA4134 (OPAx134) series are ultra-low distortion, low-noise operational amplifiers fully specified for audio applications. A true FET input stage is incorporated to provide excellent sound quality and speed for exceptional audio performance. This feature, in combination with high output drive capability and excellent dc performance, allows for use in a wide variety of demanding applications. In addition, the OPAx134 series has a wide output swing, to within 1V of the rails, allowing increased headroom and making these devices an excellent choice for use in any audio circuit.

The OPAx134 SoundPlus™ audio operational amplifiers are easy to use and free from phase-inversion and the overload problems often found in common FET-input operational amplifiers. The devices can be operated from ±2.5V to ±18V power supplies. Input cascode circuitry provides excellent common-mode rejection and maintains low input bias current over the wide input voltage range, minimizing distortion. The OPAx134 series operational amplifiers are unity-gain stable and provide excellent dynamic behavior 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.

Single and dual versions are available in 8-pin DIP and SO-8 surface-mount packages in standard configurations. The quad is available in SO-14 surface-mount package. All are specified for –40°C to +85°C operation. A SPICE macromodel is available for design analysis.
