LM49101TM/NOPB

The LM49101TM/NOPB is a low cost, high-efficiency, high output and low-noise integrated audio amplifier designed for portable multimedia and low power applications. It supports a wide input voltage range (2.7V to 5.5V) with high output current (up to 8.2mA). The amplifier also offers superior performance, including increased output power, reduced distortion, and low noise and pop noise levels. The LM49101TM/NOPB is an advanced audio amplifier integrated circuit (IC).

Application Field

The LM49101TM/NOPB can be used in a variety of different audio applications, from portable multimedia and low power systems to high-efficiency portable audio applications. It is also suitable for use in phones, PDAs, MP3 players, gaming devices, digital cameras, audio input stages, and other devices that require a low-noise, high-efficiency amplifier.

The LM49101TM/NOPB is available in a small, standard 8-7-pin MSOP package and can be used with a wide variety of passive components, including resistors, capacitors, and inductors. The device has a broad output power range (2-30V peak-to-peak) due to its low power consumption and its wide output peak current of 8.2mA. It is also able to deliver a visually stunning acoustic experience with its low noise and distortion levels.

Working Principle

The LM49101TM/NOPB utilizes the DirectDrive™ technology, which combines the voltage output stage and the current output stage in one package. This reduced solution size with its high efficiency and minimized distortion levels make it the perfect solution for low power audio applications. The device consists of numerous built-in components, including resistors, capacitors, diodes, and high gain PA stages. It works by amplifying the audio signal into a much larger current and voltage level before it is sent to the output stage. This process enables the device to provide high-quality audio amplification in a wide range of applications.

The LM49101TM/NOPB also contains an adjustable high power current bias which helps the device output more power while keeping the audio clean and distortion-free. The device also features an adjustable slow-start circuit that helps suppress pop-noise and ensures reliable start-up of the device. Furthermore, the device also has a thermal shutdown feature that enables the device to protect itself from over-heating.

The LM49101TM/NOPB also uses a feedback loop circuit to ensure the output audio signal is accurate and distortion-free. The feedback loop uses an external resistor to compare the input signal to the output. If the input voltage is different from the output voltage, then a compensating circuit is used to adjust the output so that the audio signal is exact.

Conclusion

In conclusion, the LM49101TM/NOPB is an advanced, low-noise, high-efficiency audio amplifier IC designed for portable multimedia and low power applications. It is capable of producing a high output current of 8.2mA with minimal distortion and low noise and pop-noise levels. Its DirectDrive™ technology and adjustable high power current bias make it highly efficient while providing superior performance and a visually stunning acoustic experience. The device also features an adjustable slow-start circuit, thermal shutdown and a feedback loop circuit for accurate, distortion-free audio output.
