Operation with 2.5V supply, it can drive 200mw into a mono 8Ω. The BTL configuration eliminates the need for external coupling capacitors on the output in most applications. The MS6891 is unity-gain stable and can be configured by external gain-setting resistors. The MS6891 has good feature for portable equipment, these features include the low voltage operation, micropower consumption shutdown mode, small package SOP8, MSOP8, make the MS6891 ideally suited for use in portable electronic equipments.
