The LM4905MM/NOPB is an audio amplifier lineardevice used to increase the power level of anaudio signal. It is a dual-channel, low-impedanceaudio amplifier that operates from a +5V to +12Vsingle battery supply. Its power output can beset from 2.5 watts to 8 watts per channel. TheLM4905MM/NOPB features protection andoperating features, such as under-voltage, atemperature-compensated shutdown, andover-voltage, along with short-circuit, thermaland transient protection.

The LM4905MM/NOPB is a dual channel audioamplifier powered by a single +5V to +12V powersupply. The LM4905MM/NOPB has acommon-mode rejection ratio (CMRR) of 60dBand an overall gain of 40dB, which makes it wellsuited for audio applications where low noiseand wide dynamic range are required. The poweroutput can be set from 2.5 W to 8 W perchannel.

The LM4905MM/NOPB features Tone Stage Control,which is a feature commonly found in highend audio amplifiers. This feature provides theability to adjust the gain of the amplifier from 0to 10 dB, allowing precise adjustment of theaudible balance between the low and highfrequencies. Additionally, the LM4905MM/NOPB features an output power limiter, which simplifysthe process of controlling the output power of theamplifier and prevents any unnecessary blow-upspeakers or damage to the device.

The LM4905MM/NOPB\'s work principle is based on the concept of signal amplification. The audio signal is applied to the amplifier\'s input and a voltage gain is applied to the signal. This resulting signal is then applied to the amplifier\'s output where it is amplified again and drives the speaker. The gain of the amplifier is determined by the user through the tone stage control.

The LM4905MM/NOPB is suitable for any audio application, such as car sound systems, home audio systems, portable audio players and multiple speaker systems. Its dual channel design and low power consumption make it an ideal choice for these applications. Additionally, its protection features make it well suited for automotive applications where it is highly likely that the device will be subjected to high temperatures and extreme voltages.

The LM4905MM/NOPB is a powerful audio amplifier and has been widely used in the audio industry. Its dual channel design and wide dynamic range make it well suited for applications that require low noise and high fidelity. Its protection features ensure that it is suitable for use in automotive applications where it will be subjected to high temperatures and wide voltage variations.
