[Remarks]

*1: For 1-channel operation

*2: Unless otherwise specified, use a constant-voltage power supply to supply power when inspections are carried out.

*3: The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50Hz)

power supply should be used to minimize the influence of AC primary side flicker noise on the reading.

*4: Use the transformer power supply circuit shown in the figure below for allowable load shorted time measurement.

*5: Please connect –Pre VCC pin (#1 pin) with the stable minimum voltage and connect so that current does not flow in

by reverse bias.

* Thermal design must be implemented based on the conditions under which the customer’s end products are expected

to operate on the market.

* A thermoplastic adhesive is used to adhere the case.
