AS1703 - 1.8W Single-Channel Audio Power Amplifiers

Download the AS1703 datasheet PDF (AS1702 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for 1.8w single-channel audio power amplifiers.

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.

Features

  • 2.7V to 5.5V (VCC) Single-Supply Operation THD+N: 1.8W into 4Ω at 1% (per Channel) Differential Input Adjustable Gain Option (AS1702) Internal Fixed Gain to Reduce External Component Count (AS1703, AS1704, AS1705).

Datasheet 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 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 4Ω load with less than 1% total harmonic distortion (plus noise), while operating from a single 2.7 to 5V supply.
