5. NOTE ON CORRECT USE
5.1 Pin Processing of Unused Circuit
The input/output pins of an unused circuit must be processed as specified below.
A pull-down or pull-up resistor is connected inside to the logic input pins. Connect the input pins to the GND or LV
DD
(IN
IR1
and IN
IR2
) potential when they are not used.
A pull-down resistor is not connected to the RESETB pin. Be sure to fix the RESETB pin to the LV
DD
or GND
potential when it is used.
5.2 OUT
4S
pin
Keep the voltage in the OUT
4S
pin to 2 V or less.
If an application circuit like the one shown below is used, the input voltage range of the amplifier is also 2 V or less.

5.3 OFFSET SHIFT OF AMP3
In case of large current with H-bridge 3, it cause to small offset shift in AMP3. Please take care to use AMP3, and
estimate actual set deeply.
