Introduction

AI Translation

The MAX9718/MAX9719 differential input audio power amplifiers are ideal for portable audio devices with internal speakers. The differential input structure improves noise rejection and provides common - mode rejection. A bridge - tied load (BTL) architecture minimizes external component count, while providing high - quality, power audio amplification. The MAX9718 is a single - channel amplifier while the MAX9719 is a dual - channel amplifier for stereo systems. Both devices deliver 1.4W continuous average power per channel to a 4Ω load with less than 1% THD + N while operating from a single +5V supply. The devices are available as adjustable gain amplifiers or with internally fixed gains of 0dB, 3dB, and 6dB to reduce component count.
