The OPA134UAE4 is a high-performance audio operational amplifier designed by Texas Instruments. This op-amp is widely recognized for its low distortion, low noise, and high-speed specifications, making it an ideal choice for professional audio equipment, studio mixers, and high-quality audio preamplifiers.

Key Features

• FET Input: The OPA134UAE4 features a FET input stage which ensures high input impedance and low bias currents. This is particularly beneficial for audio applications as it minimizes the loading of the source circuit.
• Low Distortion: With a total harmonic distortion (THD) of less than 0.00008%, the OPA134UAE4 provides exceptionally clean and accurate audio reproduction, preserving the integrity of the original signal.
• Low Noise: A low voltage noise density of 8nV/√Hz at 1kHz ensures that the signal is amplified with minimal added noise, which is crucial for high-fidelity audio applications.
• Wide Bandwidth: The device offers a wide bandwidth of 8MHz, which allows it to handle a broad range of audio frequencies without compromising signal quality.
• High Slew Rate: A slew rate of 20V/μs enables the OPA134UAE4 to respond quickly to changes in the input signal, which is important for maintaining the clarity and dynamic range of audio signals.
