Digital Input Class-D Amplifier with IV Feedback and Brownout Protection MAX98388/MAX98389 General Description The MAX98388/MAX98389 is a small, cost-effective mono digital input amplifier with integrated IV feedback. The device operates over a wide supply voltage range from 2.3V to 10V. With this supply range, both versions support single-cell, two-cell, and externally regulated/boosted portable applications. MAX98388 is optimized for up to 5.5V applications (single-cell), while MAX98389 is optimized for 5V to 10V cases (two-cell). The Class-D playback amplifier pairs Class-AB level audio performance with the efficiency needed to extend battery life in portable applications.
