MAX9713ETJ

Audio Amplifiers Overview

The MAX9713ETJ is a mono Class D audio power amplifier manufactured by Analog Devices Inc. (Maxim Integrated). It delivers up to 8W of output power into an 8-ohm load and 6W into a 4-ohm load, utilizing a filterless design with spread spectrum modulation to minimize EMI. The device operates from a single supply voltage ranging from 4.5V to 26V. It features differential inputs, depop circuitry, shutdown, and mute functions. Packaged in a 32-pin TQFN (5x5mm) with an exposed pad for thermal management.

Audio Amplifiers Feature Summary

• Filterless operation enabled by spread spectrum modulation for reduced electromagnetic interference
• Differential input architecture providing high noise immunity
• Integrated protection mechanisms including thermal shutdown and short-circuit protection
• Depop circuitry eliminates speaker popping during power transitions

Audio Amplifiers Applications

• Portable multimedia devices requiring high efficiency
• Compact audio systems with space constraints
• Battery-powered consumer electronics
• Desktop speakers and soundbars

Audio Amplifiers Procurement Notes

Verify the specific suffix (+T or -T) against the required reel quantity and RoHS compliance status. Confirm the package variant matches the PCB footprint requirements. Ensure the source document explicitly states the active status and operating temperature range for the intended environment.

Audio Amplifiers Selection Notes

Select this component when board space is limited due to its filterless topology. Choose the mono configuration if only a single channel is required. Consider the 32-pin TQFN package for thermal performance in compact enclosures. Verify that the load impedance matches the specified power ratings for optimal efficiency.

Audio Amplifiers Part Context

This part belongs to the MAX9713/MAX9714 family of Class D amplifiers. The MAX9713 provides mono output, while the MAX9714 offers stereo capability. Both share similar efficiency and protection features but differ in channel count and pin configuration. They are designed to replace traditional Class AB amplifiers in portable applications.

Audio Amplifiers Replacement Considerations

Direct substitutes include the MAX9714ETJ for stereo applications with compatible pinouts. Check for updated revisions from Analog Devices for improved thermal characteristics. Ensure any replacement maintains the same 32-pin TQFN footprint and supply voltage range.
