[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 and output
noise voltage measurement.
*5:
The impression voltage of ‘#13 (Stand-By) pin’ must not exceed the maximum rating.
Power amplifier operate by impressing voltage +2.5 to +5.5V to ‘#13 (Stand-By) pin’.
*6:
Please connect -PreVCC pin (#1 pin)with the stable minimum voltage, and connect so that current does not flow in
by reverse bias.
*7:
Thermal design must be implemented based on the conditions under which the customer’s end products are expected
to operate on the market.
*8:
The case of this Hybrid-IC is using thermosetting silicon adhesive (TSE322SX).
