2W STEREO AUDIO
AMPLIFIER
CMOS IC
„ DESCRIPTION
As a stereo audio speaker which is operating on a single 5V
supply, the UTC PA3428 is capable of delivering 2W of output
power per channel into 4Ω loads with less than 1% THD+N.
Way of two terminals (GAIN0 and GAIN1) can configured and
control the amplifier gain. It also provide gain settings of 2, 6, 12,
and 24V/V.
Other features include internal gain control which requires few
external components, an active-low shutdown mode input and
thermal shutdown protection.
