Audio Amplifiers datasheet and documents for MAX98400BETG+

MAX98400BETG+

Audio Amplifiers Overview

The MAX98400BETG+ is a stereo Class D audio amplifier from Analog Devices/Maxim Integrated, housed in a 24-pin TQFN package. It delivers 2x12W into 8Ω loads or 2x20W into 4Ω loads. Operating on a single supply voltage ranging from 8V to 28V, the device achieves up to 90% efficiency at 12V. Key electrical characteristics include a 67dB power-supply rejection ratio (PSRR), low quiescent current of 15mA, and comprehensive protection against thermal overload and overcurrent conditions.

Audio Amplifiers Feature Summary

Integrated clipping limiter prevents output distortion and protects speakers from transient voltages
Filterless modulation design passes EN55022B EMI limits with minimal external components
Thermal foldback feature automatically reduces output power above +130°C junction temperature
Comprehensive click-and-pop suppression minimizes audible transients during shutdown transitions

Audio Amplifiers Applications

LCD/PDP televisions
LCD monitors
MP3 docking stations
Notebook PCs

Audio Amplifiers Procurement Notes

Verify the specific suffix ETG+ corresponds to the 24-pin TQFN package variant when sourcing. Confirm that the ordering information matches the MAX98400B specifications rather than the MAX98400A, as pinouts and performance metrics differ between the two models. Ensure compatibility with the required 8V to 28V supply range for your target application.

Audio Amplifiers Selection Notes

Select this component for applications requiring high-efficiency stereo amplification without complex output filters. The MAX98400B is suitable for systems needing 12W per channel into 8Ω loads. Consider the MAX98400A if higher power output (20W per channel) or mono configuration capabilities are required instead.

Audio Amplifiers Part Context

This part belongs to the MAX98400 series of high-power Class D amplifiers designed for thermally efficient audio solutions. The series includes variants like the MAX98400A, which offers higher power output and mono operation capabilities. Both devices share similar control interfaces and protection features but differ in maximum power delivery and package configurations.
