MAX9701ETG+T

Audio Amplifiers Overview

The MAX9701ETG+T is a stereo Class D audio amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.5V to 5.5V and delivers up to 2.2W per channel into a 4-ohm load. The device features differential inputs, pop-and-click suppression, and integrated short-circuit and thermal protection. It is housed in a 24-TQFN (4x4) surface-mount package with an exposed pad for thermal dissipation. The component supports operation across a temperature range of -40°C to +85°C.

Audio Amplifiers Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against official distributor catalogs before procurement. Confirm RoHS3 compliance status and REACH registration requirements for your region. Check for obsolescence notices or lifecycle changes from Analog Devices. Ensure the 24-TQFN footprint matches your PCB design guidelines. Validate that the differential input interface aligns with your system's signal source specifications.

Audio Amplifiers Selection Notes

Select this component when a stereo Class D solution is required for low-voltage portable applications. The differential input capability makes it suitable for noisy environments where single-ended inputs may suffer from interference. Consider the 2.2W per channel output power rating relative to the speaker impedance and desired volume levels. Evaluate the thermal performance requirements given the TQFN package size and exposed pad design for heat dissipation.
