UNISONIC TECHNOLOGIES CO., LTD PA3212 2.6W STEREO AUDIO 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.
