It can automatically switch between mono 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 MS6853’s gain is set by external gain-setting resistors. The MS6853 has good feature for portable equipment, these features include the low voltage operation, micropower consumption shutdown mode, enhance thermal pad and small package MSOP10, TSSOP14, make the MS6853 ideally suited for use in portable digital audio equipments.
