MAX9703ETJ+T

Audio Amplifiers Overview

The MAX9703ETJ+T is a mono Class D audio power amplifier in a 32-pin TQFN package. It operates on a single supply voltage ranging from 10V to 25V with a quiescent current of 14mA and shutdown current of 0.2µA. The device delivers up to 15W continuous output power into an 8Ω load at 16V, achieving up to 78% efficiency. Key electrical parameters include 0.07% THD+N, 80dB PSRR at 1kHz, and SNR exceeding 95dB. It features differential inputs, pin-selectable gain, and spread-spectrum modulation.

Audio Amplifiers Feature Summary

• Filterless operation utilizing proprietary modulation schemes that eliminate the need for bulky output filters
• Spread-spectrum mode reduces EMI-radiated emissions compared to conventional fixed-frequency methods
• Comprehensive click-and-pop suppression ensures quiet startup and shutdown sequences
• Integrated short-circuit and thermal-overload protection safeguards against fault conditions

Audio Amplifiers Applications

• LCD TVs
• LCD Monitors
• Desktop PCs
• LCD Projectors
• Hands-Free Car Phone Adapters

Audio Amplifiers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this variant, as the datasheet primarily lists the tube-packaged MAX9703ETJ+. Confirm the manufacturer's current production status and lead times directly with Analog Devices or authorized distributors, as availability may vary.

Audio Amplifiers Selection Notes

Select the MAX9703ETJ+T for mono-channel high-power applications requiring filterless design. Ensure the system supports the 10V to 25V single-supply range. Verify that the speaker load impedance and inductance meet the requirements for optimal filterless performance and thermal management within the -40°C to +85°C operating range.

Audio Amplifiers Part Context

This component belongs to the MAX9703/MAX9704 family of Class D amplifiers designed to combine Class AB performance with Class D efficiency. The MAX9703 variant provides mono output, while the MAX9704 offers stereo capability. Both share similar architectures but differ in package dimensions and channel configuration.

Audio Amplifiers Replacement Considerations

The MAX9704ETJ+ serves as the stereo counterpart within the same family. Designers should verify pin compatibility and thermal requirements when substituting between mono and stereo variants.
