APA2031

APA2030/2031 Stereo 2.6W Audio Amplifier(With Gain Control) Features • Low operating current with 6mA • Improved depop circuitry to eliminate turn-on transients in outputs • High PSRR • Internal gain control, eliminate external components. • 2.6W per channel output power into 3Ω load at 5V, BTL mode • Multiple input modes allowable selected by HP /LINE pin (APA2030) • Two output modes allowable with BTL and SE modes selected by SE/BTL pin (for APA2030 only) • Low current consumption in shutdown mode (50µ A) • Short Circuit Protection • T SSOP-24-P (APA2030) and TSSOP-20-P (APA2031) with thermal pad package. General 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 3Ω 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 the SE/BTL input 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.
