Function
In C-couple type power amplifiers, it is necessary to give the output condenser C a large capacity to
flatten out the frequency characteristics to the low frequency band (this is because the loss in the low
frequency bandwidth becomes larger due to the effect of the high-pass filter comprising C and RL).
Particularly when the headphone load is approximately 16 W and an attempt is being made to achieve
frequency characteristics of ±3 dB at 20 Hz, a large capacity condenser of C = 470 mF is required.
Bearing this situation in mind, a low-pass compensation function was built in to the TA2131FN, and
while reducing the capacity of the output coupling condenser, almost flat (±3 dB) frequency
characteristics in all audible bandwidths (20 Hz to 20 kHz) have been achieved.
Fig.3 shows the low-pass system diagram, and Fig.4 shows the frequency characteristics at each point.
In Fig.4, (a) represents the status lost by the low-pass as a result of the high-pass filter comprising
the headphone load (RL = 16 W) and the output coupling condenser (220 mF) in the C-coupling system.
