4-CHANNEL ACTUATOR MOTOR DRIVER

EXPLANATION OF OPERATION

1.The characteristics between Control voltage and Output voltage

CH1,CH2,CH4 AMP.

CH3 AMP.

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.
