TPA6113A2DR is an audio amplifier designed for portable and home audio applications based on BCDMOS technology. It is a 3-channel amplifier that is stereo wired or bridge, yielding up to a 4W output power and supply range from 1.8V to 3.6V. This amplifier has a low power consumption, small size, low distortion and high output power, making it suitable for small-sized portable audio applications.

The TPA6113A2DR amplifier is divided into two sections, input and output. The input section includes an Input Overvoltage Protection (IOP) mechanism that is designed to protect the input stage from excessive input signals. The amplifier also includes a protection circuit which may be used to limit the output voltage when the input voltage exceeds a certain level. The output section contains a power amplifier stage which is connected to a single-ended output stage, producing an amplified output signal. Since the TPA6113A2DR amplifier is a 3-channel amplifier, it can be used as a stereo pair or a bridged amplifier.

The power amplifier stage uses a two-channel differential BCDMOS amplifier for providing the required linearity and dynamic performance. It consists of two identical full-bridge transistors, each with its own gain stage. The input signals are applied to the input stage, which is then amplified and rectified in the power amplifier stage. The rectified and amplified signal is then applied to the output stage, where it is further amplified and then sent to the speaker.

The TPA6113A2DR amplifier has a high power efficiency, low distortion and high output power, making it an ideal choice for applications such as portable audio, home audio and automotive audio. The amplifier also has a low output noise and low sensitivity to supply voltage variation, making it suitable for battery operated systems. The amplifier can also operate over a wide temperature range, making it suitable for both indoor and outdoor applications.

The TPA6113A2DR amplifier is easy to use and is designed for easy integration into a variety of applications. The amplifier can be easily configured for stereo or bridge mode and the input and output stages can be configured for optimal performance, depending on the application. The amplifier also has a built-in mute, power save mode, and thermal shutdown to protect the amplifier from overheating and damage.

In summary, the TPA6113A2DR amplifier is an ideal choice for portable and home audio applications. It has a low power consumption and is suitable for operating in a wide range of temperatures, making it perfect for both indoor and outdoor applications. The amplifier is also able to provide high output power in stereo or bridge mode, making it suitable for a variety of applications.
