The LM4952TSX/NOPB is an audio amplifier primarily intended for mobile applications, such as headsets, earbuds, and portable speakers. It is a single-chip audio power amplifier that is designed to provide low voltage, low power amplification of audio signals. It provides a high efficiency, low distortion audio amplifier that is ideal for a wide range of applications in the audio market.

The LM4952TSX/NOPB is a dual audio power amplifier that integrates two channels of audio power amplifiers, one stereo and one mono amplifier, into a single 14-pin package. The amplifier is designed to provide up to 2 Watts of total power into 8 Ohm speakers. The amplifier is capable of driving up to 4 Ohm loads with reduced output power and has a typical THD+N of 0.1%.

The LM4952TSX/NOPB features both active-low enable and mute control pins to enable the user to precisely control the output power of the amplifier. The mute pin can be used to attenuate the output power to reduce the power consumption when the amplifier is not in use. The amplifier is also equipped with a thermal shutdown feature that will shut down the amplifier if it overheats and can be re-enabled with a reset control pin.

The LM4952TSX/NOPB is designed to be integrated into mobile or portable audio systems such as portable speakers or earbuds. The amplifier can be powered directly from the device’s battery and can be biased using a voltage divider or a separate reference voltage. The amplifier can be directly connected to the output of the audio codec, or it can be used to drive transducers such as speakers and headphones.

The LM4952TSX/NOPB also features a number of protection and fault control features to safeguard the amplifier against unexpected operating conditions. The amplifier is protected from short circuits, thermal overloads, and overvoltage protection. It also features under-voltage protection to ensure that the amplifier does not turn on in the case of a low voltage supply. Furthermore, the LM4952TSX/NOPB has a fault detection circuit that can be used to indicate the presence of an abnormally conducting load on the output.

The LM4952TSX/NOPB is a highly efficient and reliable audio power amplifier designed to provide low voltage, low power amplification of audio signals. It can be used in a variety of audio applications such as headsets, earbuds, and portable speakers. The amplifier features both active-low enable and mute control pins, under-voltage protection, and a thermal shutdown feature. The LM4952TSX/NOPB also provides protection from short circuits, thermal overloads, and overvoltage protection, as well as a fault detection circuit for detecting abnormally conducting loads on the output.
