Key Featrues
Single-Supply Operation (2.4V to 5.5V): The MAX9722A/MAX9722B operates efficiently on a single supply voltage ranging from 2.4V to 5.5V, making it ideal for portable devices where battery life and power efficiency are critical. This feature ensures compatibility with a wide range of power sources, enhancing versatility in various applications.
High PSRR (80dB at 217Hz): With an impressive power-supply rejection ratio (PSRR) of 80dB at 217Hz, the MAX9722A/MAX9722B effectively minimizes noise from digital power supplies. This eliminates the need for an additional linear regulator, reducing system complexity and cost while maintaining high audio quality.
DirectDrive® Architecture: The unique DirectDrive® architecture allows the amplifier to produce ground-referenced outputs from a single supply, eliminating the need for large DC-blocking capacitors. This saves board space, reduces component height, and lowers overall system cost, making it ideal for compact portable devices.
Integrated Click-and-Pop Suppression: The MAX9722A/MAX9722B includes comprehensive click-and-pop suppression circuitry, which ensures a smooth and noise-free audio experience during startup and shutdown. This feature enhances user satisfaction by preventing disruptive audio artifacts in portable audio equipment.
±8kV ESD-Protected Amplifier Outputs: The amplifier outputs are protected against electrostatic discharge (ESD) up to ±8kV (Human Body Model), ensuring robust durability in real-world applications. This protection reduces the risk of damage during handling or operation, improving reliability and longevity in portable devices.
