[Remarks]
*1: Unless otherwise specified, use a constant-voltage power supply to supply power when inspections are carried out.
*2: 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.
*3: Use the designated transformer power supply circuit shown in the figure below for allowable load shorted time and
output noise voltage measurement.
*4: Use the standby pin (pin 1) so that the applied voltage never exceeds the maximum rating.
The power amplifier is turned on by applying +2.5V to +5.5V to the standby pin (pin 1).
*5: The -Pre VCC (pin 6) must be at the lowest level under any circumstances so that the reverse-bias current does not
flow.
* Thermal design must be implemented based on the conditions under which the customer’s end products are expected
to operate on the market.
* The weight of hybrid IC alone: 15g
