MAX9796EBX+TG45

Audio Amplifiers Overview

The MAX9796EBX+TG45 is a high-efficiency Class D mono audio power amplifier combined with a mono DirectDrive receiver amplifier and a stereo DirectDrive headphone amplifier. It delivers 2.3W into a 4Ω load from a 5V supply, achieving up to 80% efficiency. The device operates on a single supply voltage ranging from 2.7V to 5.5V. It features active emissions limiting and spread-spectrum modulation to reduce EMI without output filtering. The package is a 36-bump UCSP (3mm x 3mm), specified over an operating temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Utilizes unique spread-spectrum modulation and active emissions limiting to significantly reduce electromagnetic interference.
• Features a fully differential input architecture with comprehensive click-and-pop suppression for clean audio transitions.
• Provides flexible user-defined mixer configuration and volume control via an I2C digital interface.

Audio Amplifiers Applications

• Cell Phones
• Portable Multimedia Players
• Handheld Gaming Consoles

Audio Amplifiers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Confirm current availability status as distribution channels may list limited stock or end-of-life conditions. Ensure compatibility with system voltage requirements and I2C bus specifications before integration.

Audio Amplifiers Selection Notes

Select this component when space-constrained designs require integrated speaker, receiver, and headphone amplification. The UCSP package minimizes board area. Verify that the required output power aligns with the 4Ω or 8Ω load capabilities at the target supply voltage. Ensure the application benefits from the elimination of external DC-blocking capacitors provided by the DirectDrive outputs.

Audio Amplifiers Part Context

This part belongs to Maxim Integrated's third-generation ultra-low EMI Class D audio amplifier family. It combines multiple audio functions into a single chip to simplify design and reduce bill of materials. The DirectDrive technology allows ground-referenced outputs from a single supply, distinguishing it from traditional amplifiers requiring complex coupling networks.

Audio Amplifiers Replacement Considerations

Consult official manufacturer substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering generic Class D audio subsystems.
