-description: |
-  The RT9120 is a high efficiency, I2S-input, stereo audio power amplifier
-  delivering 2*20W into 8 Ohm BTL speaker loads. It supports the wide input
-  voltage  range from 4.5V to 26.4V to meet the need on most common
-  applications like as TV, monitors. home entertainment, electronic music
-  equipment.
