PA3017
2W STEREO AUDIO AMPLIFIER
DESCRIPTION
As a stereo audio speaker which is operating on a single 5V
supply, the UTC
PA3017
is capable of delivering 2W of output
power per channel into 3Ω 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 6 dB, 10 dB, 15.6 dB,
and 21.6 dB (inverting). Other features include internal gain control
which requires few external components, an active-low shutdown
mode input and thermal shutdown protection.
CMOS IC
