Stereo 2.8W Audio Power Amplifier with DC Volume Control and Selectable Gain
Features * * * * * * *
Operating Voltage : 3.3V to 5V Stereo switchable bridged/single-ended power amplifiers DC Volume Control Interface , 0dB to -105dB Low Supply Current , IDD = 13mA at Stereo BTL Low Shutdown Current , IDD = 0.7A Bridge-Tied Load (BTL) or Single-Ended-(SE) Modes Operation Output Power at 1% THD+N , VDD=5V
General Description
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 control , 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 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 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).
