• Utilizes spread-spectrum modulation to significantly reduce electromagnetic interference emissions
• Features fully differential architecture with integrated click-and-pop suppression
• Includes I2C interface for programmable gain, mute, mono/stereo, and mix functions

Audio Amplifiers Applications

• Cellular Phones
• Notebook PCs
• PDAs
• Handheld Gaming Consoles

Audio Amplifiers Procurement Notes

Verify the specific suffix 'BEUI' against official documentation to confirm pinout and package variations. Ensure the component is sourced from authorized distributors to guarantee authenticity. Confirm that the lead-free '+T' designation matches project requirements. Validate the operating temperature range of -40°C to +85°C against environmental specifications.

Audio Amplifiers Selection Notes

Select this component when a combined solution for both speaker and headphone amplification is required in a compact form factor. The DirectDrive architecture eliminates the need for large DC-blocking capacitors, reducing board space and cost. Consider the I2C programmability for flexible system configuration and the low-power shutdown mode for battery-operated applications.

Audio Amplifiers Part Context

The MAX9702 belongs to Maxim Integrated's DirectDrive family of audio amplifiers. This series focuses on providing high-performance audio solutions with minimal external components. The integration of Class D and Class AB amplifiers in a single package addresses the dual-audio needs of portable consumer electronics efficiently.

Audio Amplifiers Replacement Considerations

The MAX9702ETI+ is a documented alternative within the same product line. Verify compatibility regarding the I2C slave address and package dimensions before substitution.
