MAX9777ETI+T is a high-performance, cost-effective, multiple-channel audio amplifier designed specifically for automotive applications. It is a single-channel class-D power amplifier capable of providing up to 700 Watts of output power. This amplifier provides excellent performance in terms of THD+N, low noise, and low output impedance, making it ideal for use in automotive infotainment systems.The MAX9777ETI+T is a step-by-step linear amplifier which features a three-stage architecture. The first stage is a differential input stage which amplifies the input signal using two complementary MOSFETs. This stage is followed by a gain stage composed of two MOSFETs, where the signal is amplified by up to 20dB. Finally, the last stage is a class-D output stage which converts the amplified signal into high-power, high-efficiency audio.The MAX9777ETI+T is designed to offer high efficiency, low power consumption, and superior sound quality. To achieve this, the amplifier utilizes high-performance components and cutting-edge design techniques. The PWM controller used in the amplifier is designed to minimize switching losses and provide a high level of output power efficiency. The integrated feedback loop minimizes distortion, allowing the amplifier to deliver clean, distortion-free audio even at full output levels.In addition, the MAX9777ETI+T is designed to be highly robust and reliable. The amplifier features an integrated thermal management system which is designed to ensure that the amplifier operates within its specified temperature range. The amplifier also features an integrated over-temperature protection circuit which ensures that the amplifier does not overheat when operated for extended periods of time.The MAX9777ETI+T is an ideal choice for automotive applications and home audio systems, offering superior sound quality and excellent thermal performance. The amplifier is capable of producing up to 700 Watts of output power and features low distortion and noise levels. The amplifier is also highly reliable and robust, featuring an integrated thermal management system and an over-temperature protection circuit. With its high performance, low cost, and superior sound quality, the MAX9777ETI+T is the ideal choice for automotive and home audio applications.
