The MAX9716/MAX9717 audio power amplifiers are ideal for portable audio devices with internal speakers. A bridge-tied load (BTL) architecture minimizes external component count, while providing high-quality audio reproduction. Both devices deliver 1.4W continuous power into a 4 load with less than 1% Total Harmonic Distortion (THD) while operating from a single +5V supply. With an 8 load, both devices deliver 1W continuous power. These devices also deliver 350mW continuous power into an 8 load while operating from a single +3.0V supply. The devices are available as adjustable gain amplifiers (MAX9716/MAX9717A) or with internally fixed gains of 6dB, 9dB, and 12dB (MAX9717B/ MAX9717C/MAX9717D), reducing component count.
