MAX9705AETB+

Audio Amplifiers Overview

The MAX9705AETB+ is a high-performance, single-channel Class D audio power amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates on a supply voltage range of 2.5V to 5.5V and delivers up to 2.3W of output power into a 4-ohm load. The device utilizes a compact 10-TDFN (3x3mm) surface-mount package with an exposed pad for thermal management. Key electrical specifications include a wide operating temperature range from -40°C to +85°C and compliance with RoHS3 standards. It integrates differential inputs and protection features such as thermal shutdown and short-circuit protection.
