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.
