Key Featrues
Low Noise (8 nV/√Hz): With a low noise floor, the OPA134 minimizes unwanted interference, making it ideal for high-precision audio circuits. This enhances the signal-to-noise ratio, resulting in cleaner and more accurate audio output.
True FET-Input Stage (IB = 5pA): The FET-input design provides superior sound quality and speed, reducing input bias current and minimizing distortion. This makes the amplifier suitable for applications requiring high input impedance and low noise.
Wide Supply Range (±2.5 V to ±18 V): The OPA134 can operate across a broad range of supply voltages, offering flexibility in various audio systems. This versatility allows it to be used in both low-power and high-performance designs.
High Output Drive Capability (Iout = 0.04 A): The amplifier's ability to drive significant loads ensures robust performance in demanding audio applications. This feature is particularly beneficial for driving headphones, speakers, or other high-impedance audio components.
Applications
Active Audio Filters: The OPA134's high speed (20 V/µs slew rate and 8 MHz bandwidth) and excellent dynamic behavior make it suitable for designing active audio filters. Its wide supply range (±2.5 V to ±18 V) allows for flexible implementation in both portable and high-power audio systems.
Professional Audio Mixers: With its high output drive capability and excellent DC performance, the OPA134 is well-suited for professional audio mixers. Its ability to handle high load capacitance and maintain low distortion ensures clear and accurate audio mixing in live sound and recording environments.
Headphone Amplifiers: The OPA134's wide output swing, to within 1 V of the rails, and low noise characteristics make it an excellent choice for headphone amplifiers. Its superior sound quality and low distortion ensure an immersive listening experience, ideal for high-end personal audio devices.
