Derating Curves
Precautions
1) Unused circuits
2) Input terminal voltage
3) Power supply (single / dual)
4) Power dissipation Pd
5) Short-circuit between pins and erroneous mounting
6) Terminal short-circuits
7) Operation in a strong electromagnetic field
8) Radiation
9) IC handing
10) Board inspection
When there are unused circuits it is recommended that they be
connected as in Fig. 6, setting the non-inverting input terminal
to a potential within the in-phase input voltage range (VICR).
Applying GND + 36V to the input terminal is possible without causing
deterioration of the electrical characteristics or destruction, irrespective of
the supply voltage. However, this does not ensure normal circuit operation.
Please note that the circuit operates normally only when the input voltage is
within the common mode input voltage range of the electric characteristics.
The op-amp operates when the specified voltage supplied is between Vcc and GND. Therefore, the single supply op-amp can be used as a dual supply
op-amp as well.
Using the unit in excess of the rated power dissipation may cause deterioration in electrical characteristics due to a rise in chip temperature, including
reduced current capability. Therefore, please take into consideration the power dissipation (Pd) under actual operating conditions and apply a sufficient
margin in thermal design. Refer to the thermal derating curves for more information.
Incorrect mounting may damage the IC. In addition, the presence of foreign particles between the outputs, the output and the power supply, or the output and
GND may result in IC destruction.
When the output and Vcc terminals are shorted, excessive output current may flow, resulting in undue heat generation and, subsequently, destruction.
Operation in a strong electromagnetic field may cause malfunctions.
This IC is not designed to withstand radiation.
Applying mechanical stress to the IC by deflecting or bending the board may cause fluctuations in the electrical characteristics due to piezoelectric (piezo)
effects.
Connecting a capacitor to a pin with low impedance may stress the IC. Therefore, discharging the capacitor after every process is recommended. In addition,
when attaching and detaching the jig during the inspection phase, ensure that the power is turned OFF before inspection and removal . Furthermore, please
take measures against ESD in the assembly process as well as during transportation and storage.
