TPA3111D1PWPR Integrated Circuit Chip 10W Filter-Free Mono Class-D Audio Power Amplifier With Speaker Guard™

TPA3111D1PWPR Integrated Circuit Chip 10W Filter-Free Mono Class-D Audio Power Amplifier With Speaker Guard™

Product Description Of TPA3111D1PWPR
TPA3111D1PWPR device is a 10-W, efficient, Class-D audio power amplifier for driving a bridge tied speaker. Advanced EMI suppression 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 lets the user to set a virtual voltage rail lower than the chip supply to limit the 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.
