It can automatically switch between dual BTL and stereo SE modes utilizing a headphone sense pin. The BTL configuration eliminates the need for external coupling capacitors on the output in most applications. The unity gain stable MS6863’s gain is set by external gain-setting resistors. The MS6863 has good feature for portable equipment, these features include the low voltage operation, micropower consumption shutdown mode, enhance thermal pad and small package TSSOP20, make the MS6863 ideally suited for use in portable audio equipments. The MS6863 has an extra selection for pin7 to achieve pop noise free in shutdown control.
