MAX9768ETG+T

Audio Amplifiers Overview

The MAX9768ETG+T is a mono 10W Class D speaker amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 4.5V to 14V supply and delivers up to 10W into an 8Ω load at 14V. The device features a 64-step dual-mode volume control, selectable spread-spectrum modulation for EMI reduction, and filterless output capability. Electrical specifications include 77dB PSRR, 0.08% THD+N, and 97dB SNR. It is housed in a 24-pin thin QFN-EP (4mm x 4mm) package with an operating temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Integrated 64-step volume control supporting both analog voltage and I2C digital programming modes.
• Selectable spread-spectrum modulation reduces EMI emissions to meet EMC standards with ferrite bead filters.
• Filterless modulation topology eliminates the need for external LC output filters.
• Robust protection mechanisms including short-circuit and thermal-overload safeguards.

Audio Amplifiers Applications

• Notebook Computers
• Flat-Panel Displays
• Multimedia Monitors
• GPS Navigation Systems
• Security/Personal Mobile Radio

Audio Amplifiers Procurement Notes

Verify the specific suffix 'ETG+T' against the manufacturer's current ordering guide to confirm package type and tape-and-reel quantity. Confirm RoHS compliance status as per the latest datasheet revision. Check production lifecycle status, as availability may vary. Ensure the supplier provides valid traceability documentation for the component batch.

Audio Amplifiers Selection Notes

Select this component for applications requiring high-efficiency audio amplification without external output filtering. Consider the 64-step volume control interface requirements when designing the system bus or analog control circuitry. Evaluate the thermal performance on the PCB layout, as power dissipation depends on the board layer configuration. Verify that the supply voltage range aligns with the system battery or power rail specifications.
