Features

General
• Operating voltage from 8 to 18 V
• Low distortion
• Few external components, fixed gain
• Automatic mode selection (SE or BTL) depending on connected ‘rear’ loads
• Can be used as a stereo amplifier in Bridge-Tied Load (BTL) or quad Single-Ended (SE) amplifiers
• Single-ended mode without loudspeaker capacitor
• Soft clipping, to guarantee good clip behaviour with inductive loads
• Mute and standby mode with one-pin operation
• Diagnostic information for Dynamic Distortion Detector (DDD), high temperature (140 °C) mode of operation and short-circuit
• No switch-on/off plops when swit.
