LM4881M/NOPB is a 2 Watt stereo audio amplifier based on the BTL architecture. The LM4881M/NOPB is a monolithic 7-pin audio amplifier. The film and polymer film technology used in its manufacture ensure superior audio quality comparable to discrete amplifiers. This amplifier has excellent sound fidelity, low distortion and has low pass filter characteristics for cutoff frequencies of 20 kHz and 8 kHz.

The LM4881M/NOPB amplifier features an input gain of 26 dB and an output gain of 24 dB. It is able to produce up to 2 W per channel using 4V to 8V supply voltage. The device is protected against overheating and overcurrents with shutdown and thermal shutdown features. The LM4881M/NOPB amplifier features low power audio amplifiers with low resistance imaging voltage designed to reduce design complexity and maximize low distortion operation.

The LM4881M/NOPB application field includes digital music players, personal computers, active loudspeakers, digital pianos, portable audio systems and other audio applications where superior sound quality is required. It is easy to use and has minimal power rating requirements, making it suitable for a wide range of applications. Furthermore, its integrated filter makes it suitable for digital signal processing.

In terms of its working principle, the LM4881M/NOPB is a Class B amplifier. It works by allowing current to flow in two directions. The two currents produce a desirable output signal. The signal is then amplified by the transistors that are connected to the Class B amplifier. The output of the amplifier is amplified in two directions and its signal is then sent to the output terminals. The sound quality is improved by the filtering capabilities of the amplifier.

The LM4881M/NOPB audio amplifier is ideal for audio systems that require high fidelity sound. It is also suitable for a wide range of applications due to its easy integration, low power rating requirements, and low distortion capability. Its high performance characteristics make it an excellent choice for audio applications.
