1.8W Single-Channel Audio Power Amplifiers

1 General Description
The AS1702 - AS1705 are single-channel differential audio power-amplifiers designed to drive 4 and 8 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 common-mode rejection. A bridge-tied load (BTL) design minimizes external component count, while providing high-fidelity audio power amplification. The devices deliver 1.8W continuous average power per channel to a 4 load with less than 1% total harmonic distortion (plus noise), while operating from a single 2.7 to 5V supply. For reduced component designs, the devices are available with different gain levels as shown in Table 1. Table 1.
