The input cut-off frequency is:
Application: R
As shown in
switch-on delay during charging of the input capacitors can be minimized. This results in a
good low frequency response and good switch-on behavior.
The power amplifier is a Single-Ended (SE) amplifier with an all-NPN output stage,
capable of delivering a peak output current of 3 A.
The output power as a function of the supply voltage is measured on the output pins at
THD = 10 %; see
26 V and the maximum available output current is 3 A (repetitive peak current). A
minimum load of 3
measured with one channel driven.
