MAX9736AETJ/V+T

Audio Amplifiers Overview

The MAX9736AETJ/V+T is a mono/stereo high-power Class D audio amplifier from Analog Devices/Maxim Integrated. It delivers up to 2 x 15W into 8Ω loads or 1 x 30W into a 4Ω load. The device operates from an 8V to 28V supply range and provides high PSRR, eliminating the need for a regulated power supply. It offers up to 88% efficiency at a 12V supply. Pin-selectable modulation schemes allow selection between filterless modulation and classic PWM modulation. Comprehensive click-and-pop reduction circuitry minimizes noise during shutdown or mute transitions.

Audio Amplifiers Feature Summary

• Pin-selectable modulation schemes enable operation in either filterless mode or classic PWM mode.
• Spread-spectrum modulation flattens wideband spectral components to improve EMI performance.
• Comprehensive click-and-pop suppression minimizes audible transients during startup and shutdown.
• Mono configuration allows parallel channel operation with an uncommitted operational amplifier available.

Audio Amplifiers Applications

• LCD/PDP/CRT Monitors
• LCD/PDP/CRT TVs
• MP3 Docking Stations
• Notebook PCs
• PC Speakers

Audio Amplifiers Procurement Notes

Verify the specific suffix 'V+T' against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels may vary. Ensure the ordering information matches the exact part number requirements for your design specifications.

Audio Amplifiers Selection Notes

Select this component when high power output and thermal efficiency are required without heatsinks. Consider the pin-selectable modulation for EMI optimization or audio quality preferences. Verify that the 8V to 28V supply range aligns with system power constraints. Evaluate the 32-pin TQFN package size for board space limitations.

Audio Amplifiers Part Context

The MAX9736 series includes variants like MAX9736B and MAX9736D with different power outputs. The MAX9736A specifically targets higher power applications compared to the B/D versions. All variants share similar features but differ in maximum output power capabilities based on the load resistance and supply voltage conditions.

Audio Amplifiers FAQ

How does the MAX9736 handle EMI in filterless mode?

It uses spread-spectrum modulation to flatten wideband spectral components, allowing it to pass CE EMI limits with low-cost ferrite bead and capacitor filters.

What happens to the right-channel preamplifier in mono mode?

In mono mode, the right-channel preamplifier becomes an uncommitted operational amplifier, providing flexibility for system design tasks such as summing amplifiers or filters.
