4. Current feedback channels(channel 4 & 5)
The reference voltage(ref) is given externally through pin 22.
The input OP-amp output signal is amplified by (20K/10K) times and then fed to the current feedback amplifier.
The current feedback amplifier compares the output current sensed input and command input then makes the controlled
output to eliminate delay effect of the load. Please refer to the application note for more information about current feedback
theory(http://www.fairchildsemi.com/an/AN/AN-4109.pdf).
The DC gain of current feedback amplifier and power amplifier is unity, that is 1 [A/V]. Users can change the gain by
adding external resistor at the command input.
5. Channel 2 & 3 schematic
The reference voltage(ref) is given externally through pin 22.
The input OP-amp output signal is amplified by (12K/10K) times and then fed to the power amplifier. The gain of power
amplifier is 4 so the total max gain of channel 2 and 3 is 8.
