Tpa3113d2 Amplifier

With the support of our expert, our company is dedicated Supplier of TPA3113D2 Amplifier in Shenzhen, Guangdong, China.
1. Description
The TPA3113D2 is a 6-W (per channel) efficient,Class-D audio power amplifier for driving bridged-tied stereo speakers.
Advanced EMI Suppression Technology enables the use of inexpensive ferrite bead filters at the outputs while meeting
EMC requirements. Speaker Guard speaker protection circuitry 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.
