Tpa3140d2pwpr inductive stereo (BTL) class D audio amplifier has the lowest price
explain
Tpa3140d2 is a class D audio power amplifier suitable for bridging stereo speakers with up to 10W, 6 Ω or 8 Ω (per channel).
The * * EMI suppression technology with spread spectrum control and 1spw modulation scheme not only meets the EMC requirements, but also supports the use of low-cost ferrite bead filter in the output, so as to reduce the system cost.
Tpa3140d2 not only provides comprehensive protection against short circuit and overload, but also speakerguard ™ The speaker protection circuit also includes an adjustable automatic gain limit (AGL), an adjustable power limiter and a DC detection circuit to protect the connected speakers. AGL can adjust the larger output voltage without signal clipping, so as to enhance the speaker protection effect and improve the audio quality. DC detection and pin to pin, pin grounding and pin to power short circuit protection circuits can prevent the speaker from output DC and pin short circuit in the production process. At the same time, fully protect the output to prevent GND, PVCC and output to output short circuit. Short circuit protection and thermal protection have automatic recovery function.
Tpa3140d2 can drive stereo speakers with impedance as low as 4 Ω. The efficiency of tpa3140d2 is up to 90% at a load of 8 Ω, no external radiator is required, and tpa3140d2 can realize full power output on double-layer printed circuit board (PCB).
