[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 designated transformer power supply circuit shown in the figure below for the measurement of allowable

load shorted time and output noise voltage.

*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.

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

to operate on the market.

*7: Be sure to use the current limiting resistor to prevent the current flowing into the standby pin (pin13) never exceeds

the maximum rated value in operating mode.

The circuit is turned on by applying VBE (approximately 0.6V) or higher voltage to the standby pin (pin13).

*8: A thermoplastic adhesive resin is used for this hybrid IC.
