PAM8408DR is a two-channel low-voltage audio amplifier with a maximum output power of 6.0 W at 28 V. The PAM8408DR integrates a low-power standby mode as well as shutdown logic. It features thin and compact size, precise volume control and a wide voltage range, making it suitable for many different types of audio applications.

The PAM8408DR is part of a family of low-voltage audio amplifiers and is the most suitable for use in the audio field. These amplifiers are designed to operate in the very low voltage range down to 1.8 V, allowing small form factor portable devices to have clear, crisp and powerful music reproduction.

The PAM8408DR provides an extremely easy way to apply audio amplification in a wide range of applications. It has an adjustable gain and is protected against short circuits and input overvoltage. Additionally, it can operate up to -40°C to 85°C temperature range and is ideal for low-cost, low-power applications, handsets, portable audio players, computers and other battery-powered devices.

The PAM8408DR unit is composed of three basic components: the power stage, the output stage and the power supply management. The power stage is composed of two matched power transistors, which drive the load, while the output stage consists of one or more control and protection circuits. The power supply management module, which is highly integrated in the device, manages the power supply, so that it can operate with different levels of supply voltage and current.

The PAM8408DR works by amplifying the input signal to a higher level as it passes through the power stage. The output stage receives the amplified signal and further amplifies it, which is then transmitted to the load. This allows for higher levels of output power, with minimal distortion and less heat dissipation.

The PAM8408DR features an adjustable gain control which allows users to set the gain according to the application. The adjustable gain feature ensures a better control over the output amplitude of the audio signal. Apart from that, the PAM8408DR also has internally set protection circuits that prevent it from various conditions such as over-current, over-voltage, temperature and output short-circuiting. It also has a low-power standby mode which reduces power consumption when the device is not in use.

The PAM8408DR is the perfect choice of audio amplifier for applications requiring low-voltage operation and maximum efficiency. With its small form factor, precise volume control and adjustable gain, it is a perfect solution for low-power audio applications in both portable and home audio devices.
