LM4667ITL/NOPB Application Field and Working Principle

The LM4667ITL/NOPB is a high-performance audio amplifier designed to drive differential output stages with high accuracy, low noise, and low distortion. It features low power consumption in a small package and is widely used in audio applications such as multichannel headphone amplifiers, automotive car audio systems, home theater systems, and professional audio equipment. The amplifier is operated in a differential mode and is optimized for low distortion, high output power, and low power consumption.

The LM4667ITL/NOPB operates in a three-stage differential configuration. The first stage is a differential input stage, consisting of two input transistors and an active current source for biasing. The input stage provides high-gain, low-noise performance. The second stage consists of two differential current mirrors, each driving an output transistor, which provides a high-voltage swing and low output impedance. The third stage is a voltage feedback stage, which provides extended frequency response and low distortion. The amplifier uses complementary metal oxide semiconductor (CMOS) processing to achieve low distortion and noise.

The LM4667ITL/NOPB features excellent dynamic range, low distortion, and low output noise. It can drive headphones with wide dynamic range, low distortion, and low noise floor. The input and output are optimized for low output impedance and high voltage gain, while is also feature short-circuit protection, thermal overload protection, and over-voltage protection for increased safety.

The LM4667ITL/NOPB operates in the audio frequency range from 20 Hz to 20 kHz. The input is compatible with any audio source, from 20 Hz to 20 kHz, and is designed for high-fidelity performance and low distortion. This makes it ideal for consumers who want to get the highest quality sound out of their audio system.

In conclusion, the LM4667ITL/NOPB is a high-performance, low power consumption audio amplifier that is well suited for audio applications such as multichannel headphone amplifiers, automotive car audio systems, home theater systems, and professional audio equipment. It features low distortion, high output power, and low power consumption. The amplifier is optimized for low distortion, high output power, and low power consumption, all while delivering excellent dynamic range, low distortion, and low output noise.
