Key Featrues
Low Quiescent Current: The MAX9725A–MAX9725D models operate with a quiescent current of 2.1mA, while the MAX9725E operates at 2.3mA. This low current consumption enhances battery life in portable devices, making it ideal for applications like smartphones and MP3 players.
Single-Cell, 0.9V to 1.8V Single-Supply Operation: The amplifier can operate efficiently from a single-cell power supply ranging from 0.9V to 1.8V. This feature simplifies power management in portable electronics and reduces the need for additional voltage regulation components.
DirectDrive® Architecture: The DirectDrive technology eliminates the need for large DC-blocking capacitors by producing a ground-referenced output from a single supply. This reduces board space, component height, and overall cost, while maintaining high audio quality.
Integrated Click-and-Pop Suppression: The amplifier includes built-in click-and-pop suppression, which minimizes audible noise during power-up and shutdown sequences. This enhances the user experience by providing cleaner audio transitions in portable audio equipment.
High PSRR (80dB at 1kHz): The high Power Supply Rejection Ratio (PSRR) of 80dB at 1kHz ensures that the amplifier is less susceptible to noise and fluctuations in the power supply. This results in clearer and more stable audio output, particularly in noisy environments.
