The MS6894 is a fully differential power amplifier that can drive 1.1W of continuous average power into a mono 8 bridged-tied load (BTL). Operation with 2.5V supply, it can drive 200mw into a mono 8 . The shutdown may be enabled by either logic high or logic low that depending on shutdown mode selection. The BTL configuration eliminates the need for external coupling capacitors on the output in most applications. The MS6894 is unity-gain stable and can be configured by external gain-setting resistors. The MS6894 has good feature for portable equipment, these features include the fully differential input, low voltage operation, micropower consumption shutdown mode, enhance thermal pad and small package MSOP10, make the MS6894 ideally suited for use in portable electronic equipments.
