maintainers:
- ChiYuan Huang <cy_huang@richtek.com>
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.
