FAQ


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 1V of the rails, allowing increased headroom and making it ideal for use in any audio circuit.
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 600Ω loads.

Distortion Measurements

The distortion produced by OPA134 series of operational amplifiers is below the measurement limit of all known commercially-available equipment. However, a special test circuit can extend the measurement capabilities. Operational amplifier distortion can be considered an internal error source which can be referred to the input.

Phase Reversal Protection

The OPA134 series of operational amplifiers are free from output phase-reversal problems. Many audio operational amplifiers, such as the OP176, exhibit phase-reversal of the output when the input common-mode voltage range is exceeded. This can occur in voltage-follower circuits, causing serious problems in control loop applications. The OPA134 series operational amplifiers are free from this undesirable behavior even with inputs of 10-V beyond the input common-mode range.

OPA2134PA Applications

The OPA134 series operational amplifiers are unity-gain stable, and suitable for a wide range of audio and general-purpose applications. All circuitry is independent in the dual version, assuring normal behavior when one amplifier in a package is overdriven or short-circuited. Power supply pins should be bypassed with 10-nF ceramic capacitors or larger to minimize power supply noise.
Application examples: Audio, Communications & Networking, Signal Processing
The OPAx134 family offers outstanding dc precision and AC performance. These devices operate up to 36-V supply rails and offer ultralow distortion and noise, as well as 8-MHz bandwidth and high capacitive load drive. These features make the OPAx134 a robust, high-performance operational amplifier for high-voltage professional
audio applications.


OPA2134PA Design Requirements

• Gain = 5 V/V (inverting)
• Low pass cutoff frequency = 30 kHz
• –40 db/dec filter response
• Maintain less than 3-dB gain peaking in the gain versus frequency response
