Bit LS_GAIN BRIDGE CONFIGURATION EXPLAINED The LM49120 loudspeaker amplifier is designed to drive a load differentially, a configuration commonly referred bridge-tied load (BTL). The BTL configuration differs from the single-ended configuration, where one side of the load ...
Page 24
POWER DISSIPATION Power dissipation is a major concern when designing a suc- cessful single-ended or bridged amplifier. A direct consequence of the increased power delivered to the load by a bridge amplifier is higher internal power dissipation. The LM49120 has ...
