Applications
RFI Protection
Figure 3 shows the THAT 1200 configured with
robust RFI input protection.
RFI rejection is of less concern, the circuit shown Fig-
ure 4 provides a less aggressive approach.
In applications where
Bootstrap coupling capacitor
Referring to Figure 3, electrolytic capacitor Cb
provides the feedback path for the boostrap circuit.
The capacitor value is chosen to be high enough to
present a sufficiently small impedance to signals at
the low end of the audio spectrum. Its voltage rating
is dependent on the topology of the surrounding cir-
cuitry, as described in the following paragraphs.
AC signals presented to the input stage cause the
two ends of capacitor Cb to swing in tandem so that
virtually no voltage appears across the capacitor.
Consequently, capacitors with small DC working volt-
ages may be used when the previous stage is AC cou-
pled to the input of the THAT 1200.
