LM4877ITP/NOPB is an audio amplifier that has a wide range of applications. It is a buffer amplifier designed specifically for high current applications and is capable of supplying up to 400mA of current. It has a wide gain bandwidth, low distortion and a fast slew rate. It is designed to securely drive loudspeakers, providing a low output impedance. The LM4877ITP/NOPB can be configured as either a single ended amplifier or as a bridged amplifier.

The LM4877ITP/NOPB is capable of driving loudspeakers from 2 ohm to 8 ohm and can operate from either dual supply rails or single supply rail. It can also be used with a passive bypass circuit for higher Currents. The amplifier can be used in a variety of applications, including automotive audio systems, home theatre systems, desktop music systems, speaker phones and circular audio systems.

The LM4877ITP/NOPB has an open loop gain of 100dB, a slew rate of 400V/s and a voltage gain of 20dB. It also has a low noise figure of 0.5dB, very low distortion of THD+N 0.2%. The power output of the LM4877ITP/NOPB is determined by its load impedance, with a maximum power output of 0.5W into 8 ohm loads. The minimum load impedance that the amplifier can drive is 2ohms, with a maximum power output of 1W into a 2 ohm load.

The LM4877ITP/NOPB is designed to be used in combination with either a Low Voltage Low Cost power supply or a High Voltage Low Cost Power Supply. When used with a Low Voltage Low Cost power supply, the amplifier is capable of supplying 800mA of current, which is sufficient for driving most speaker systems. When used with a High Voltage Low Cost power supply, the amplifier is capable of supplying 1A of current and is suitable for use with more demanding speaker systems.

The LM4877ITP/NOPB operates from a supply voltage of 5V to 18V, with a maximum supply current of 800mA. It is constructed as a surface mount package with a 9mm x 9mm footprint, which makes it suitable for mounting on any PCB or other flat surface.The amplifier has Thermal Shutdown protection and Short Circuit protection, which prevents damage should it be accidentally connected up to a speaker with an incorrect impedance.

In summary, the LM4877ITP/NOPB is a suitable audio amplifier for a wide range of applications. It has a wide bandwidth, low distortion, fast slew rate, and can drive loudspeakers from 2 ohm to 8 ohm. The amplifier can be used with either a Low Voltage Low Cost power supply or a High Voltage Low Cost power supply, and is suitable for use in a variety of audio applications.
