• Description: 4-CHANNEL ACTUATOR MOTOR DRIVER
• Manufacturer: Mitsubishi

EXPLANATION OF OPERATION
1.The characteristics between Control voltage and Output voltage
The input Amp.(Vctl terminal)consists of the non-inverted Amp. and
the output(VM+,VM-) is amplified by the different voltage between
Vref and Vctl. The voltage gain of this input Amp. is 1 time.
Also,the output Amp. is the Master-Slave constitution.Each of
Master Amp.(VM+) and Slave Amp. (VM-)have the gain of 10 times
and the output voltage is about (Vcc-0.7)/2.

The three terminals(Inverted,non-inverted and output)of Input Amp.
go to external pins. So,the Amp. constitution (for example, Buffer
Amp.) and the Gain can be adjusted by the external resistors.
The output Amp., the same with CH1, 2 and 4, consist of the
Master-Slave Amp.
Each of the Master-Amp.(VM+) and Slave Amp.(VM-) have the
gain of 2.66 and the output voltage is about (Vcc-0.7)/2.
