stereo class-D audio power amplifier

power to at 4? from a 5.5V supply in a Bridge Tied Load (BTL) configuration. Under same conditions, the amplifier can provide 1.4W to an 8 BTL load with less than 1% THD+N. For portable applications it offers space and cost savings because no output filter is required when using inductive speakers. With more than 90% efficiency and very low shutdown current, it increases the life time of your battery. The NMP-4011 processes analog inputs with the unique pulse-width modulation method that lowers output noise and EMI. The gain can be reduced by external input resistors. The NMP-4011 provides thermal and short circuit protection.
