The TMS8213E is a Stereo 3.1W Class D audio power amplifier for driving bridged-tied speakers and includes a Stereo Class AB amplifier for driving headphones. The advanced 64 steps DC volume control minimizes external components allowing simple and accurate volume control over the gain range of +20dB to -80dB.
The TMS8213E features Non-clipping Power Limiting (NCPL) which detects output signal clip due to the over input level and keep the output none clipping automatically to get the excellent sound quality and protect the speaker to be damaged.
Advanced Spread Spectrum Modulation (SSM) EMI suppression technology with soft-driving scheme enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC/EMI requirements for system cost reduction.
The outputs are fully protected against shorts to ground, supply, and output-to-output. The short-circuit protection and thermal protection includes an auto recovery feature.
The TMS8213E is available in the power efficient and space saving 3x3 and 4x4 QFN-20 packages.
