As a stereo audio speaker which is operating on a single 5V
supply,
the UTC PA3431 is capable of delivering 2W of output
power per channel into 4Ω loads in Bridge-Tied Load (BTL) mode
with less than 1% THD+N.
Way of two terminals (GAIN0 and
GAIN1) can configured and control the amplifier gain. It also
provided BTL gain settings of 6 dB, 10 dB, 15.6 dB, and 21.6 dB
(inverting). Other features: the SHDN mode is supported to disable
UTC PA3431 for the low current consumption applications;
the
current consumption can be reduced to typically 150µA.
