AMPLIFIER WITH FOUR

SELECTABLE GAIN SETTINGS

AND MUX CONTROL

CMOS IC

„ DESCRIPTION

As operating on a single 5V supply, the UTC PA3212 is

capable of delivering 2.6W of output power per channel into 3Ω

loads. In Bridge-Tied Load (BTL) mode the UTC PA3212 has less

than 1% THD+N, and it also has less than 0.65% THD+N across

its specified frequency range when driving 1 W into 8-Ω speakers.

Way of two terminals (GAIN0 and GAIN1) can configure and

control the amplifier gain. It also provides BTL gain settings of 2,

6, 12 and 24 V/V.

Other features included that the SHDN mode is provided to

disable UTC PA3212 for the low current consumption applications

and the current consumption can be reduced to typically 150µA.
