Product Summary

The MAX9718AETB is a differential input audio power amplifier. It is ideal for the portable audio device with internal speaker. The differential input structure of the MAX9718AETB improves noise rejection and provides common-mode rejection. A bridge-tied load (BTL) architecture minimizes external component count, while providing highquality, power audio amplification. The MAX9718AETB is a single-channel amplifier. The MAX9718AETB is available as adjustable gain amplifier or with internally fixed gains of 0dB, 3dB, and 6dB to reduce component count. The applications of the device include Mobile Phones, PDAs and Portable Devices.
