The LM4675TLX/NOPB is a monolithic power amplifier designed to provide an audio solution for both commercial and industrial applications. It is an integrated, Class-AB audio power amplifier and can provide up to 20W of audio output power.

This amplifier is designed specifically for driving small, low-impedance loads, such as headphones and mobile phones. The amplifier\'s circuit also includes noise rejection circuitry and short-circuit protection to ensure that the output noise is minimized and operation is safe.

This versatile Class-AB amplifier is available in various packages and allows for a wide range of designs. It is suitable for use in applications such as car audio systems and multimedia applications. It features an adjustable gain control, protection circuitry and low-noise performance, making it an ideal choice for cost-sensitive, power amplifier applications.

The LM4675TLX/NOPB offers an efficient single-ended Class-AB audio power amplifier capable of delivering up to 20W of continuous output power. The device is capable of driving both 4 and 8 ohm loads, making it a perfect choice for small power amplifier applications.

The LM4675TLX/NOPB features a high-current, single-ended output stage for low impedance loads, a VCC current limiting function, thermal protection, and a shutdown mode. The device also includes an adjustable gain setting, adjustable power limits, and adjustable short-circuit protection. It includes a wide supply voltage range of 3.0V to 20.0V and an adjustable output current of up to 2A.

The LM4675TLX/NOPB also provides a differential amplifier output capable of driving 8 ohm speakers in single or bridged mode or 4 ohm speakers in bridged mode. The device also has a high power-supply rejection ratio of 80 dB which makes it suitable for applications in noisy or contaminated supply environments.

The LM4675TLX/NOPB works on the principle of using two transistors connected in series as a push-pull amplifier. The input signal is applied to the base of the first transistor, forming the inverted signal, which is then connected to the base of the second transistor to form the non-inverted signal. As this signal is then amplified, the output is produced. The bias current is set by the amplifier\'s external components, allowing the transistors to operate efficiently and provide the desired output power.

The LM4675TLX/NOPB is a high-performance, cost-effective option for audio amplification applications. It features an adjustable gain control, low-noise performance, and an adjustable output current of up to 2A. With its wide supply voltage range of 3.0V to 20.0V and its high-current, single-ended output stage, it is the perfect choice for small power amplifier applications.
