... The APA2071 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo bridged audio power amplifiers capable of producing 2.6W (1.8W) into 4 The attenuator range of the volume control in APA2071 is from 18dB (V steps. The advantage of internal gain setting can be less components and PCB area. Both the depop circuitry and ...

... IC. Forward Over-Current Protection The APA2071 monitors the output current. When the cur- rent exceeds the current-limit threshold, the APA2071 turns off the output to prevent the IC from damages in over- current or short-circuit condition. When the over-current occurs in power amplifier, the output buffer’ ...

... F or greater near the audio power amplifier Optimizing Depop Circuitry Circuitry has been included in the APA2071 to minimize the amount of popping noise at power-up and when com- ing out of shutdown mode. Popping occurs whenever a voltage step is applied to the speaker. In order to elimi- nate clicks and pops, all capacitors must be fully dis- charged before turn-on ...

... Copyright ANPEC Electronics Corp. Rev. A.1 - Aug., 2008 BTL Since the APA2071 is a dual channel power amplifier, the maximum internal power dissipation is 2 times that both of equations depend on the mode of operation. Even with this substantial increase in power dissipation, the APA2071 does not require extra heatsink. The power dis- ...
