The NE5532FE is a high-performance dual operational amplifier with the following functional features:
1. Dual-channel Amplification Function: It contains two independent operational amplifiers inside, which can amplify two channels of signals simultaneously. In a dual-channel audio system, it can amplify the left and right channel audio signals respectively and is widely used in circuits that require dual-channel signal processing.
2. Low Noise Characteristic: It has very low equivalent input noise and can process weak audio signals while maintaining the clarity and accuracy of the signals. It can ensure that audio devices output high-quality audio that is pure and free of noise.
3. Low Distortion Performance: Both total harmonic distortion and intermodulation distortion are very low. When amplifying audio signals, it can maintain the quality of the original signal to the greatest extent, reproduce clear and accurate sounds, and avoid distortion of audio signals.
4. High Slew Rate: The typical slew rate is 9V/μs, which allows it to quickly track changes in input signals and respond rapidly to jumps and changes in input signals. It is suitable for processing high-frequency and fast-changing audio signals.
5. Wide Bandwidth: The gain-bandwidth product can reach 10MHz, and it can process audio signals from DC to several hundred kilohertz. It can accurately restore the frequency characteristics of audio signals, enabling audio signals of different frequencies to be effectively amplified and processed.
6. High Output Drive Capability: It can drive loads as low as 600Ω and can directly drive loads such as audio output stages, providing sufficient drive power for subsequent circuits to ensure the effective transmission and amplification of audio signals.
7. Wide Voltage Range: The operating voltage range is usually from ±3V to ±20V, which can adapt to different power supply voltage environments and provides flexibility for circuit design.
8. Short-circuit Protection Function: It has a built-in short-circuit protection circuit to prevent the amplifier from being damaged due to short circuits when driving heavy loads or in case of faults, improving the stability and reliability of the circuit.
