Power Op Amp Circuit
The circuit described utilizes the PA04 power amplifier from Apex Microtechnology, which is designed for high-performance applications requiring substantial output power and minimal distortion. The PA04 is capable of delivering an impressive 400 watts RMS into an 8-ohm load, making it suitable for driving speakers or other loads that demand high power levels.
Operating at frequencies beyond 20 kHz, the amplifier maintains low total harmonic distortion (THD), which is crucial for high-fidelity audio applications. This low distortion ensures that the output signal remains faithful to the input, providing clear and accurate sound reproduction.
The capability to deliver 180 V peak-to-peak at a frequency of 90 kHz into a 4-ohm load highlights the amplifier's versatility and robustness. This feature is particularly beneficial in applications that require significant voltage swings and rapid signal changes, such as in RF or high-frequency audio systems.
In summary, the PA04 power amplifier is engineered to provide high output power with low distortion across a wide frequency range, making it an ideal choice for demanding audio and signal amplification tasks in various electronic applications. This circuit from Apex Microtcchnology can deliver 180 V p-p @ 90 kHz into a 4- load. The PA04 can deliver 400-W RMS into an 8- load with low THD at frequencies beyond 20 kHz.
