MAX9719BEBE

Audio Amplifiers Overview

The MAX9719BEBE is a low-cost, mono or stereo audio power amplifier manufactured by Analog Devices Inc. under the Maxim Integrated brand. It delivers 1.4 watts of output power into an 8-ohm load using a bridge-tied load (BTL) configuration. The device operates on a single power supply ranging from 2.7 volts to 5.5 volts and features differential inputs for improved noise rejection. It utilizes Class-AB topology to balance efficiency with audio fidelity, achieving a total harmonic distortion plus noise of 0.002 percent at 8 ohms. The component is housed in a compact TQFN-EP-16 package suitable for surface mount applications.
