AS1705 - 1.8W Single-Channel Audio Power Amplifiers

This page provides the datasheet information for the AS1705, a member of the AS1702 1.8W Single-Channel Audio Power Amplifiers family.

Datasheet Summary

Description

The AS1702 - AS1705 are single-channel differential audio power-amplifiers 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

  • ! 2.7 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).

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.
