The LM48820TM/NOPB is a high-performance audio amplifier designed to deliver ultra-low distortion and high power efficiency in sound applications needing clean audio frequency signals. The amplifier uses the latest TI’s proprietary low-noise input circuitry, enabling it to achieve remarkably low levels of total harmonic distortion (THD). With its unique dynamic power rating, the LM48820TM/NOPB can deliver up to 3x the output power of competing products, all while being extremely energy efficient. Due to its high power capability, the LM48820TM/NOPB is ideal for use in high-end audio components and professional sound applications.

The LM48820TM/NOPB architecture is based on the concept of symmetric current-mode operation, which improves the overall audio performance. This is because symmetric current mode operation helps to deliver higher voltage swing from lower supply voltages, increasing the dynamic range and reducing noise. In addition, due to its balanced input architecture, the chip can easily handle single-ended and balanced audio signals. The LM48820TM/NOPB is designed with a high-impedance input stage to minimize mechanical vibrations and noise propagation. Furthermore, the input buffer and amplifier stages have been rigorously tested to show excellent linearity and low crosstalk.

In terms of output power, the LM48820TM/NOPB can deliver up to 200W in a mono configuration, and up to 400W when operating in bridge-tied load (BTL) mode. It also features an integrated low-noise output stage that can easily handle large signal loads. Due to its wide power capability, the LM48820TM/NOPB can be used in a variety of audio applications, such as home theater systems, sound bars and high-end speaker systems.

The LM48820TM/NOPB features several features that provide a traditional and modern audio experience. The integrated feed-forward temperature compensation circuit helps to reduce distortion in high temperature environments and can improve long-term stability. The clockedshutdown logic allows for easy and quick power sequencing. Additionally, the LM48820TM/NOPB is capable of operating from a single supply voltage, making it ideal for portable devices. To further enhance the audio experience, the LM48820TM/NOPB is equipped with an integrated input preamp, providing a consistent volume and bass boost control.

In terms of protection, the LM48820TM/NOPB has several safety features that protect the audio output from faults. The integrated thermal shutoff circuit helps to reduce thermal runaway, and is coupled to an over-current shutoff circuit to protect the audio stage from excessive current levels. Additionally, the chip features a frequency limit circuit that prevents ultrasonic or high-frequency signals from damaging the output stage.

In conclusion, the LM48820TM/NOPB is a high-performance audio amplifier designed to deliver extremely low distortion and high power efficiency in a variety of sound applications. It features a symmetric current-mode architecture that ensures high voltage swings and low noise, while being capable of delivering up to 400W of output power. Additionally, it comes with several features that provide traditional and modern audio experiences such as temperature compensations, power sequencing, and bass boost controls. The LM48820TM/NOPB is an ideal choice for use in high-end audio components and professional sound applications.
