Description

APA2112RI-TUL is a monolithic integrated circuit, designed to provide precise DC volume control and a stereo bridged audio power amplifier. It is capable of producing 2.7W (2.0W) into 3W with less than 10% (1.0%) THD+N. The attenuator range of the volume control is from 20dB (DC_Vol=0V) to -80dB (DC_Vol=3.54V) with 32 steps. The advantage of internal gain setting in APA2112RI-TUL reduces the number of components and PCB area. It also integrates depop circuitry and thermal shutdown protection circuitry to reduce pops and clicks noise during power up or shutdown mode operation.
