[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 -preV
by reverse bias
Pin (#1 pin) with the stable minimum voltage and connect so that current does not flow in
CC
* 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.
