AS1702 - AS1705 1.8W Single-Channel Audio Power Amplifiers 1 General Description The AS1702 - AS1705 are single-channel differential audio poweramplifiers designed to drive 4 and 8Ω loads. The integrated gain circuitry of these amplifiers and their small size make them ideal for 2.7- to 5V-powered portable audio devices. The differential input design improves noise rejection and provides mon-mode rejection. A bridge-tied load (BTL) design minimizes external ponent count, while providing high-fidelity audio power amplification. The devices deliver 1.8W continuous average power per channel to a 4Ω load with less than 1% total harmonic distortion (plus noise), while...
