• 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 and so

on.

ref

• The reference voltage(ref) is given externally through pin 27.

• The input OP-amp output signal is amplified by (15K/10K) times and then fed to the power amplifier. The gain of power amplifier is

4; therefore, the total max gain of channel 3 is 6.

• Users must check input command range to use max output voltage because the total gain is relatively smaller than other channels.
