DESCRIPTION
The MS6890 is a low distortion power amplifier that can drive 1.5W of continuous average power into a mono 8Ω
bridged-tied load (BTL). Operation with 2.5V supply, it can drive 0.2W into a mono 8Ω. The BTL configuration
eliminates the need for external coupling capacitors on the output in most applications. The MS6890 is unity-gain
stable and can be configured by external gain-setting resistors.
The MS6890 has good feature for portable equipment, these features include the low voltage operation, micropower
consumption shutdown mode, enhance thermal pad small package SOP8(TP), make the MS6890 ideally suited for use
in portable electronic equipments.
