The LM4673TMX/NOPB is a high power, wide bandwidth and low noise Class-D audio amplifier from Texas Instruments. It is designed for use in professional, consumer and portable audio systems where high power amplification is required. It is an ideal choice for high-performance audio systems in applications such as home theater, home stereos, computer speakers, television speakers and sound bars.

The LM4673TMX/NOPB provides an excellent performance in audio applications thanks to its high power and low distortion characteristics. It provides a maximum output power of 90W per channel, a wide bandwidth of 15Hz–80kHz and a total harmonic distortion of less than 1%. Its wide power range allows it to be used in both low-power and high-power audio systems, while its low noise characteristics make it ideal for use in high-end audio systems.

The LM4673TMX/NOPB has a low quiescent current of only 20mA, which makes it an ideal solution for battery-powered devices such as handheld digital audio players and portable audio systems. In addition, it provides a wide supply range from 4.5V up to 26V, which enables it to be used in a variety of applications.

The LM4673TMX/NOPB features an adjustable low-frequency cutoff frequency, which can be set between 2Hz and 300Hz in order to reduce the possibility of audible artifacts caused by DC bias. This feature also helps reduce power consumption by allowing the amplifier to be operated with a lower quiescent current. Additionally, it offers a slew rate of up to 80V/uS and a signal-to-noise ratio of 93dB, making it an excellent choice for high-fidelity audio applications.

At its core, the LM4673TMX/NOPB is a differential amplifier, which means it amplifies the difference between two input signals rather than amplifying the signal itself. This type of amplifier is known for its low noise characteristics, allowing it to produce high-fidelity audio with minimal distortion. It also provides a high level of input protection with over temperature and over-current protection, as well as glitch protection.

The LM4673TMX/NOPB is a great choice for high-performance audio systems due to its excellent performance characteristics. With its wide bandwidth, low noise, low distortion and adjustable cutoff frequency, it is ideal for use in both low-power and high-power audio systems. Additionally, its low quiescent current, wide supply range and protection features make it an attractive solution for many different applications.
