The MAX9700AETB+ is a low power audio amplifier used in consumer and commercial audio applications. It is a precision, low voltage, Class-AB audio power amplifier device designed for portable and other applications where DC power efficiency and low supply voltage are important. The device has three different versions and offers a wide range of applications, including handsets, personal/portable audio, and multimedia. It has long-term stability and a superior noise performance for better sound quality and fidelity. The device is versatile and suitable for high fidelity, low power audio systems.The MAX9700AETB+ features a full frequency response and a low distortion level that can be used in audiophile applications as well as portable and ADA systems. The device has a high power output of 1.3W at 8 ohms and 1.9W at 4 ohms. It also has a low self-noise to ensure a better sound quality and clarity. It has a low shutdown current, making it ideal for battery-powered applications. The device also has integrated output EMI protection for improved EMC performance.The MAX9700AETB+ has a Class-AB architecture that enables it to provide high-power output with a low quiescent current, making it highly efficient. The device is also designed to have a low operating voltage, with a 1.8V operating voltage at maximum power and a 1.3V operating voltage at 30 mW with 4 ohm load. The device also has integrated soft start and thermal protection circuitry that helps to preserve the device and the speaker system. The device uses the pulse-width modulation (PWM) excitation technique to produce low distortion and low noise level. The technique uses a PWM signal to drive the amplifier where the amplitude of the signal is modulated by the pulse width of the signal. In the MAX9700AETB+, the source signal is converted into a PWM signal and is then applied to the output transistors. The PWM signal is modulated by the pulse width, and the output transistors switch on and off rapidly to provide low distortion and low EMI. The MAX9700AETB+ has a slew rate of 16V/µs and a supply current of 160 mA, making it ideal for fast-transient response applications. The device has both a low current consumption and a high power efficiency. It also has a signal-to-noise ratio (SNR) of 95 dB, a signal-to-distortion ratio (SDR) of 95 dB, and a total harmonic distortion (THD) of 0.02%.The MAX9700AETB+ is a low power audio amplifier ideal for use in portable and automotive audio applications. It features a low disposal current, low distortion, high output power, and integrated EMI protection, making it an excellent choice for applications where audio fidelity and sound quality need to be optimized. With its versatile features and excellent performance, the MAX9700AETB+ is a top choice for use in commercial and consumer audio applications.
