Application Information
24/30
and the theoretical value of the -3dB cut-off higher
frequency is 2MHz/3 = 660kHz.
We can keep this value or limit the bandwidth by
adding a capacitor Cfeed, in parallel on Rfeed.
Then:
So, we could use for Cfeed a 220pF capacitor
value that gives 24kHz.
Now, we can calculate the value of Cb with the
formula
τb = 50kΩxCb >> τin = (Rin+Rfeed)xCin
which permits to reduce the pop and click effects.
Then Cb >> 0.8µF.
We can choose for Cb a normalized value of
2.2µF that gives good results in THD+N and
PSRR.
In the following tables, you could find three
another examples with values required for the
demoboard.
Application n°1 : 20Hz to 20kHz bandwidth
and 6dB gain BTL power amplifier
Components:
Application n°2 : 20Hz to 20kHz bandwidth
and 20dB gain BTL power amplifier
Components:
Application n°3 : 50Hz to 10kHz bandwidth
and 10dB gain BTL power amplifier
