Texas Instruments, 8-Pin PDIP OPA134PA

A range of operational amplifiers from Texas Instruments designed for high-fidelity audio applications. The devices typically feature low levels of distortion and noise together with high slew rates and wide bandwidth. They are frequently able to operate over a wide supply voltage range and include outputs capable of driving 600 Ω loads.

The Texas Instruments 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.
