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 4

Ω 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 110µA.
