OPA2134PA Product Details

The OPA134 series are ultra-low distortion, low-noise  operational amplifiers fully specified for audio  applications. A true FET input stage is 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 for use in a wide variety of  demanding applications. In addition, the OPA134 has  a wide output swing, to within 1 V of the rails, allowing increased headroom and making it ideal for  use in any audio circuit. 

The OPA134 SoundPlus™ audio operational  amplifiers are easy to use and free from phaseinversion and the overload problems often found in common FET-input operational amplifiers. They can  be operated from ±2.5-V to ±18-V power supplies. Input cascode circuitry provides excellent common-  mode rejection and maintains low input bias current  over its wide input voltage range, minimizing distortion. OPA134 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 14-pin DIP and SO-14 surface mount packages. All are specified for –40°C to 85°C operation. A SPICE macromodel is available for design analysis.
