LM4652TF

The LM4652TF is a high-performance audio power amplifier from Texas Instruments that can generate up to 2.2W of output power. It boasts a wide range of features, including high efficiency, low distortion, low noise, and the ability to drive both 6 ohm and 8 ohm speakers. This makes it a popular choice for many audio applications, from personal electronics to car audio systems.

The LM4652TF was designed for a wide range of audio applications, including portable stereo systems, car audio systems, or general-purpose sound reinforcement. It is suitable for driving any combination of up to two 4- to 6-ohm speakers, and it works with a wide range of operating voltages, from 1.8V all the way up to 28V. This makes it an excellent choice for a variety of applications.

The amplifier is powered by two separate power supplies - one for the output stages and one for the control stages. The output stages supply the power to the speaker, while the control stages control and monitor the amplifier. The control stages are also responsible for providing a power-saving shutdown mode and other features, such as temperature and under-voltage protection.

The LM4652TF utilizes an innovative audio power amplifier topology, known as a folded cascode architecutre, which has been proven to provide excellent distortion and noise performance, even at high power levels. The folded cascode architecture combines a class A input stage with a class B output stage, providing a wide range of signal-to-noise ratios and distortion figures. The amplifier also features short-circuit protection and a wide operating voltage range.

The LM4652TF is also packed with useful features that make it a great choice for audio applications. It has low THD+N figures of 0.008% at 1 kHz, and features a PSRR of up to 55dB at 1 kHz. This helps to ensure that the amplifier can operate cleanly and without interference from external sources. Additionally, the LM4652TF is protected against over-current, over-temperature and under-voltage conditions.

In addition to its great performance, the LM4652TF is also easy to use. It can be configured using the simple pin-switching options, and features a built-in diagnostic LED that indicates the status of the amplifier. The amplifier can also be remotely controlled via I²C and SPI digital interfaces, making it ideal for use in home audio and automotive applications.

The LM4652TF is a great choice for a wide range of audio applications, from personal electronics to car audio systems. Its combination of high performance, easy installation, and robust protection makes it an excellent choice for both amateur and professional audio applications.
