The LM4875 is a mono bridged audio power amplifier withDC voltage volume control. The LM4875 is capable of delivering750mW of continuous average power into an 8Ω loadwith less than 1% THD when powered by a 5V power supply.Switching between bridged speaker mode and headphone(single ended) mode is accomplished using the headphonesense pin. To conserve power in portable applications, theLM4875’s micropower shutdown mode (IQ = 0.7μA, typ) isactivated when less than 300mV is applied to the DC Vol/SDpin.
