TPA3137D2 Overview
The TPA3137D2 device is an efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers at up to 6 W, 6 Ω, or 8 Ω (per channel). Advanced EMI Suppression Technology with Spread Spectrum Control scheme enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for system cost reduction. The TPA3137D2 device is not only fully protected against shorts and...
