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.
