3. DRIVER
The gain of pre-op. Amplifier can be changed by manipulating amp input resistor or feedback resistor.
The voltage, V
REF
, is the reference voltage given by the bias voltage of the pin #6.
The level shift produces the current due to the difference between the pre amp output signal and the arbitrary reference
(bias) signal. (The current produced as +
I and
I is fed into the driver buffer. (CH1/CH4)
The current produced as +2
I and
2
I is fed into the driver buffer. (CH2/CH3)
Driver buffer drives the power TR of the output stage according to the state of the input signal.
The output stage is the BTL driver and the motor is rotating in forward direction by operating TR Q1 and TR Q4.On the
other hand, if TR Q2 and TR Q3 is operating, the motor is rotating in reverse direction.
When the output voltage of Pre-Amp (Pin 3, 12, 18, 25) is below the V
REF
, then the direction of the motor is in forward.
When the output voltage of Pre-Amp (Pin 3, 12, 18, 25) is above the V
REF
, then the direction of the motor in reverse.
The gain (A
V
) of the drive circuit is as follows.
