MAX98721EWV+T series is a high-performance audio linear amplifier used in notebooks and other portable applications. It features a unique combination of sealed plastic housing, wide-range supply voltage and low supply current. The MAX98721EWV+T is optimized for improved signal-to-noise ratio and distortion, and hence, provides superior performance for portable audio applications.The MAX98721EWV+T series is well suited for application in audio systems that includes portable media players, cordless headsets, sound cards, cell phones, speakers and other audio devices. The MAX98721EWV+T amplifier incorporates a high-performance, low-accuracy variable gain amplifier that can achieve an externally selectable gain ranging from 0dB to 40dB. The variable gain amplifier supports a wide supply voltage range and is capable of driving both low impedance (<100Ω) and high impedance (>100Ω) loads with low distortion and noise. The MAX98721EWV+T also features a low-power standby mode. In standby mode, the amplifier is able to maintain a low supply current while the amplifier is in a relatively low-noise standby condition and can be quickly reactivated when the amplifier needs to be used. The MAX98721EWV+T provides superior audio performance compared to other linear amplifier solutions. With its wide voltage range, low noise, low distortion and wide gain range, the MAX98721EWV+T is ideal for audio applications where a high-quality, low-noise amplifier is required.Application field and working principle
The MAX98721EWV+T series is an industry-leading audio linear amplifier which is ideally suited for use in portable and battery powered applications. The amplifier\'s high-performance, low-accuracy Variable Gain Amplifier (VGA) gains of 0dB to 40dB, wide voltage range, low noise and distortion make it useful in many applications such as headphones, headsets, and portable speakers.The MAX98721EWV+T works on the principle of negative feedback. The signal provided to it is inverted, amplified and then sent back to the input to provide an error signal. This error signal is used by the amplifier to adjust its output in such a way that the output is a faithful reproduction of the input signal. This negative feedback mechanism helps to ensure accurate, distortion-free reproduction of the input signal. The MAX98721EWV+T also uses the principle of a Variable Gain Amplifier (VGA). A VGA consists of an amplifier, which can provide a certain voltage gain based on the setting of a gain control knob or a gain switch. This gain control can provide a wide range of gains depending on the application. This makes the MAX98721EWV+T ideal for audio applications where varying levels of gains are necessary.The MAX98721EWV+T also incorporates a low-power standby mode. In standby mode, the amplifier is able to maintain a low supply current while the amplifier is in a relatively low-noise standby condition. This allows for improved battery performance in portable applications. Thus, the MAX98721EWV+T can be used for improved battery performance and audio performance in many applications.Overall, the MAX98721EWV+T provides excellent audio performance in many applications and is an ideal choice for applications that require high performance in a small form factor. It utilizes a combination of negative feedback, variable gain, and low power standby mode to provide increased accuracy and improved performance. The MAX98721EWV+T is well suited for use in portable media players, cordless headsets, sound cards,cell phones, speakers and other audio devices.
