Product Summary
The MAX9718FEBL+TG45 is a differential input audio power amplifier 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 MAX9718FEBL+TG45 is a single-channel amplifier. The MAX9718FEBL+TG45 delivers 1.4W continuous average power per channel to a 4W load with less than 1% THD+N while operating from a single +5V supply. The MAX9718FEBL+TG45 is available as adjustable gain amplifiers or with internally fixed gains of 0dB, 3dB, and 6dB to reduce component count. The MAX9718FEBL+TG45 is suitable for Mobile Phones, PDAs, Portable Devices.
