MOSA ELECTRONICS MS6895
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). 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.FEATURES
