MAX9724AETC+TGC1

Audio Amplifiers Overview

The MAX9724AETC+TGC1 is a stereo headphone amplifier from the DirectDrive series, manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a patented architecture to produce a ground-referenced output from a single supply, eliminating bulky DC-blocking capacitors. The device features low RF susceptibility, adjustable gain, and integrated click-and-pop suppression. It operates on a single 2.7V to 5.5V supply with a quiescent current of 3.5mA and includes a low-power shutdown mode drawing less than 0.1µA.

Audio Amplifiers Feature Summary

• DirectDrive architecture eliminates the need for external DC-blocking capacitors
• Low RF susceptibility suppresses noise demodulation from input and supply traces
• Integrated click-and-pop suppression prevents audible transients during power cycles
• Adjustable gain configuration allows flexibility in system design

Audio Amplifiers Applications

• Cellular phones
• MP3 players
• Notebook PCs
• Handheld gaming consoles
• Smart phones

Audio Amplifiers Procurement Notes

Verify the exact suffix TGC1 against official documentation, as standard listings typically use ETCP or similar codes. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the component matches the specified package type and temperature range before procurement.

Audio Amplifiers Selection Notes

Select this component for portable applications requiring space savings due to the absence of large capacitors. Consider its low RF immunity for environments with high electromagnetic interference. Verify that the adjustable gain meets the specific signal requirements of the connected audio source.

Audio Amplifiers Part Context

This part belongs to the MAX9724 family of DirectDrive stereo headphone amplifiers. It shares core functionality with variants like the MAX9724B, which has fixed gain. The family is designed for battery-powered devices where efficiency and board real estate are critical constraints.

Audio Amplifiers Replacement Considerations

Check for direct pin-compatible alternatives within the MAX9724 series, such as the MAX9724B if fixed gain is acceptable. Verify that any substitute maintains the same DirectDrive capability and RF rejection specifications.
