+
+description:
+  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.
