DESCRIPTION
The MS6894 is a fully differential power amplifier that can drive 1.1W of continuous average power into a mono 8Ω
bridged-tied load (BTL). Operation with 2.5V supply, it can drive 200mw into a mono 8Ω. 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.
