MAX9727EEP+

Audio Amplifiers Overview

The MAX9727EEP+ is a quad audio line driver utilizing DirectDrive architecture to produce ground-referenced outputs from a single supply. It operates on a 2.7V to 5.5V voltage range with a typical quiescent current of 14mA and shutdown current below 0.1µA. The device delivers 3VRMS into a 1kΩ load at 5V and 2VRMS at 3.3V, maintaining THD+N below 0.003%. Key electrical parameters include a 100dB PSRR, 109dB SNR, 3MHz gain bandwidth, and ±8kV HBM ESD protection.

Audio Amplifiers Feature Summary

• DirectDrive architecture eliminates the need for large DC-blocking capacitors by generating an internal negative supply via a charge pump.
• Integrated click-and-pop suppression circuitry minimizes audible transients during power-up and shutdown sequences.
• Active-low shutdown input reduces quiescent current consumption to less than 100nA for extended battery life in portable applications.
• Ground-referenced outputs provide symmetrical signal swing while operating from a single positive supply rail.

Audio Amplifiers Applications

• Set-Top Boxes
• Consumer and Professional Audio Equipment
• Portable Audio Devices

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm package integrity and pin alignment against the 20-pin QSOP specification. Ensure environmental compliance documentation matches the + suffix designation. Validate that the specific lot corresponds to the -40°C to +85°C temperature range requirements for your application.

Audio Amplifiers Selection Notes

Select this component when board space constraints prohibit external coupling capacitors. The DirectDrive feature simplifies design by removing bulky passive components. Verify that the required output voltage swing aligns with the available single-supply voltage. Consider the thermal performance if multiple channels are driven near maximum capacity simultaneously.
