DESCRIPTION

The MS6895 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 BTL configuration

eliminates the need for external coupling capacitors on the output in most applications. The MS6895 is unity-gain

stable and can be configured by external gain-setting resistors.

The MS6895 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 SOP8, make the

MS6895 ideally suited for use in portable electronic equipments.
