4. Current feedback channels(channel 1 & 4)
• The reference voltage(ref) is given externally through pin 27.
• 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
• The DC gain of current feedback amplifier and power amplifier is unity, that is 1 [A/V]. Users can change the gain by
5. Channel 2 schematic
• The reference voltage(ref) is given externally through pin 27.
• The input OP-amp can be used for several purposes, for example low pass filter, differential input coordinator, gain scaler
