Stereo 2.8w Audio Power Amplifier With Dc Volume Control And Selectable Gain

Stereo 2.8w Audio Power Amplifier With Dc Volume Control And Selectable Gain ,The APA4835 is a monolithic integrated circuit , which provides DC Volume Control , and a stereo bridged Audio Power Amplifiers capable of producing 2.8W (2.2W) into 3 with less than 10% (1.0%) THD+N. APA4835 includes a DC Volume Control , stereo bridge-tied and single-ended Audio Power Amplifiers , stereo docking outputs , and a selectable gain con- trol , that makes it optimally fittable for notebook PC , Multimedia monitors , and other portable applications. The Attenuator range of the volume control in APA4835 is from 0dB (DC_Vol=0.7VDD) to 105dB (DC_Vol=0V) with 32 steps. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in APA4835 , that reduces pops and clicks noise during power up or shutdown mode operation , and protects the chip from being destroyed by over temperature failure. To simplify the Audio system design , APA4835 combines a ste- reo 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. Be- sides the low supply current design to increase the efficiency of the Amplifiers , APA4835 also features a shutdown function which keeps the supply current only 0.7A (typ).
