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.
