Introduction

The MAX9850ETI+G47 offers an ideal solution for audio applications requiring high-voltage linear amplification. It is a monolithic low-noise linear amplifier designed to drive low-power audio signals in a wide range of applications. The device is designed to be able to operate in both single-ended mode for lower power output and bridge mode for higher output power. The MAX9850ETI+G47 consists of a low-noise two-stages amplifier with a low-noise current gain block in between, called the input stage. The advantage of this two-stage amplifier is that it has fewer components than a traditional three-stage amplifier, with the same output power. The device also has some protection features that help to reduce the chances of system malfunction, such as thermal shutdown and under-voltage lockout.

Application Fields

The MAX9850ETI+G47 is a device offering high output power and performance with low power consumption. It is suitable for applications such as power amplifiers, portable audio players and other low-power audio systems. It can also be used in a range of other audio applications including sound reinforcement systems, TV speakers and more. Additionally, it can be used for low-power audio instrumentation, automotive audio systems, telecommunications, industrial and medical audio applications, as well as power amplifiers.

Benefits

The MAX9850ETI+G47 offers several benefits compared to other linear amplifiers. It is designed to operate with low power consumption and is designed to be smaller than other amplifiers of similar power. Its low-noise current gain block helps to improve system performance and reduce the chances of malfunction. The device also has protection features such as thermal shutdown and under-voltage lockout, which can help to reduce the chances of system failure.

Working Principle

The MAX9850ETI+G47 consists of a two-stage amplifier with a low-noise current gain block in between, called the input stage. The first stage of the amplifier is the input stage. Here, the input signal is fed into the device and the gain of the amplifier is set. The input stage amplifies the input signal and passes it onto the second stage. The second stage amplifies the signal further and delivers the boosted signal through the output section of the device.The MAX9850ETI+G47 also has protection features that help to reduce the chances of system failure. The thermal shutdown feature will automatically shut down the device if it detects an overload or over temperature condition. The under-voltage lockout feature helps to prevent the amplifier from being overload or over temperature condition.

Conclusion

The MAX9850ETI+G47 is a low-noise, high-voltage linear amplifier designed for audio applications requiring high performance and low power consumption. It is suitable for a wide range of audio applications and has some protection features which help to reduce the chances of system malfunction. It can provide high output power and performance with low power consumption in audio applications.
