Preliminary
2W STEREO AUDIO AMPLIFIER
CMOS IC
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 4load 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.
