UNISONIC TECHNOLOGIES CO., LTD PA7469 STEREO 2.6W AUDIO POWER AMPLIFIER (WITH DC_VOLUME CONTROL) CMOS IC „ DESCRIPTION As an audio power amplifier, UTC PA7469 can provides precise DC volume control, and a stereo bridged audio power amplifiers capable of producing 2.6Ω(1.8W) into 4W with less than 10% (1.0%)THD+N. In UTC PA7469, the attenuator range of the volume control is from 20dB (DC_Vol=0V) to -80dB (DC_Vol=3.54V) with 32 steps. It also includes both of the depop circuitry and the thermal shutdown protection circuitry which can reduce pops and clicks noise during power up or shutdown mode operation. It also improves the power off pop noise and has the parts to not been destroyed by over temperature and short current failure.
