FOR SINGLE SUPPLY APPLICATION SUGGESTIONS
on above circuit. Different values can be used.
* The gain must be higher than 24dB
COMPONENT
used. C7 can be larger than 1000µF only if the supply voltage does not exceed 40V.
If the supply voltage is lower than 40V and the load is 8Ω(or more), a lower value of C2(i.e. 22µF) can be
R1, R2, R3
C2
