Texas Instruments TAS5727 25W Digital Power Amplifiers

TI TAS5727 25W Digital Power Amplifiers

Texas Instruments TAS5727 25W digital audio power amplifiers are efficient devices for driving stereo bridge-tied speakers. The TI TAS5727 features speaker equalization (EQ) that improves audio performance. These TI digital audio power amplifiers also provide two band dynamic range compression (DRC) that can be used as a power limiter and enables speaker protection, easy listening, and night-mode listening. The TAS5727 also offers autodetect, which automatically detects sample-rate changes without need for external microprocessor intervention. These TI audio power amplifiers are ideal for use in LCD TV, LED TV, and soundbar applications.
