Description

APA2030/1 is a monolithic integrated circuit, which provides internal gain control, and a stereo bridged audio power amplifiers capable of producing 2.6W (1.9W) into 3 with less than 10% (1.0%) THD+N. By control the two gain setting pins, Gain0 and Gain1, The amplifier can provide 6dB, 10dB, 15.6dB, and 21.6dB gain settings. The advantage of internal gain setting can be less components and PCB area. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in APA2030/1, that reduces pops and clicks noise during power up or shutdown mode operation. It also improved the power off pop noise and protects the chip from being destroyed by over temperature and short current failure. To simplify the audio system design APA2030 combines a stereo bridge-tied loads (BTL) mode for speaker drive and a stereo single-end (SE) mode for headphone drive into a single chip, where both modes
are easily switched by theSE/BTLinput control pin signal. Besides the multiple input selections is used for portable audio system. APA2031 eliminates both input selection and single-end (SE) mode function to simplifying the design and save the PCB space.
