The MAX9789CETJ+ is an ultra low voltage single ended class AB audio power amplifier from Maxim Integrated. It is designed to provide high quality analog audio output with low power consumption for portable audio applications such as mobile phones, media players and multimedia speakers. The amplifier can provide up to 23mW of continuous average output power into a 16Ω load and up to 3V of differential output swing. The control of the audio gain is done through a single pin in the system.The MAX9789CETJ+ is designed to operate with a 3V to 3.6V single supply voltage and with less than 1μA of quiescent current. It has a wide frequency response of 20Hz to 100kHz. The amplifier features a low harmonic distortion of 0.06% at 1kHz and 0.015% at 10kHz. The device also has an adjustable gain range that can be set anywhere between -29dB to +20dB.The MAX9789CETJ+ is well suited for low voltage, cost optimized applications such as mobile phones, portable multimedia players and multimedia speakers. It can be used as a stand-alone amplifier or as part of a larger audio system. The amplifier can be integrated easily into many audio systems due to its low power consumption and low voltage operation.The working principle of the MAX9789CETJ+ is relatively simple. The input signal is fed into an input stage where it is conditioned by a pair of precision low-noise op-amps. This input stage controls the gain of the amplifier so that it can be easily adjusted to fit the specific requirements of the application. The input then passes to an output stage, which is a class AB amplifier composed of an N-channel MOSFET and a P-channel MOSFET. These devices are connected in an audio amplifier configuration and are driven by a separate power supply to provide more efficient power consumption. The output stage amplifies the incoming signal to generate the audio output.The MAX9789CETJ+ is an excellent choice for low power, low voltage audio applications such as mobile phones, media players and multimedia speakers. It is designed for easy integration and offers high quality audio output with extremely low power consumption. The adjustable gain makes it ideal for many different applications and the wide frequency response ensures accurate reproduction of music and sound. The low harmonic distortion and low quiescent current makes it an ideal cost-effective solution for audio applications.
