Product InformationFeatures
SpeakerGuard is a trademark of Texas Instruments. Description
The TPA3111D1 is a 10-W efficient, Class-D audio power amplifier for driving a bridge tied speaker. Advanced EMI Suppresion Technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements. SpeakerGuard™ speaker protection system includes an adjustable power limiter and a DC detection circuit. The adjustable power limiter allows the user to set a "virtual" voltage rail lower than the chip supply to limit the amount of current through the speaker. The DC detect circuit measures the frequency and amplitude of the PWM signal and shuts off the output stage if the input capacitors are damaged or shorts exist on the inputs. The TPA3111D1 can drive a mono speaker as low as 4 View All Description in Datasheet |
