description:
  The RTQ9128 is a ultra-low output noise, high-efficiency, four-channel
  class-D audio power amplifier and delivering 4x75W into 4OHm at 10%
  THD+N from a 25V supply in automotive applications.

  The RTQ9154 is the family series of RTQ9128. The major change is to modify
  the package size. Beside this, whole functions are almost all the same.
