| description: |
| RT9123 is a 3.2W mono Class-D audio amplifier that features high efficiency |
| and performance with ultra-low quiescent current. The digital audio interface |
| support various formats, including I2S, left-justified, right-justified, and |
| TDM formats. |
| |
| RTQ9124 is an ultra-low output noise, digital input, mono-channel Class-D |
| power amplifier that supports a 2.1MHz switching frequency. It integrates |
| both DC and AC load diagnostics, as well as real-time load monitoring to |
| assess speaker condition. The device operates from 4.5V to 18V and delivers |
| up to 30W output power. |
