APA2030

APA2030/2031 Stereo 2.6W Audio Amplifier (With Gain Control) Features General Description 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 (50µA) Short Circuit Protection TSSOP-24P (APA2030) and TSSOP-20P (APA2031) with Thermal Pad Packages. Lead Free and Green Devices Available (RoHS Compliant) Applications Notebook PCs LCD Monitor 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 controlling 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 improves 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...
