CMOS IC

2W STEREO AUDIO AMPLIFIER

DESCRIPTION

The UTC PA3427 is a stereo audio speaker operated on a single

5V supply. It is capable of delivering 2W of output power per channel

in Bridge-Tied Load mode into 4Ω load with less than 1% THD+N.

Two terminals (GAIN0 and GAIN1) can configure and control the

amplifier gain. In order to simplify the design of audio system in the

notebook application, the two modes of Bridge-Tied Load (BTL) and

Single-End (SE) mode drive the speakers and headphone

respectively. The UTC PA3427 supports two input paths to choose

two different amplitude AC signals through setting HP/LINE pin.

The UTC PA3427 is suitable for applications, such as stereo

power amplifiers of notebooks or desktop computers, and multimedia

monitors.
