Transposing and solving for the external components we get:
Treble stage
The treble stage is a high-pass filter whose time constant is fixed by an internal resistor
(25 kΩ typically) and an external capacitor connected between treble pins and ground.
Typical responses are shown in
Pin CREF
The suggested value of 10 µF for the reference capacitor (C
can be reduced to 4.7 µF if the application requires faster power-on.
