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 the measurements of allowable load shorted time and output noise voltage. *4: Design circuits so that (|VH|-|VL|) is always less than 40V when switching the power supply with the load connected. *5: Set up the VL power supply with an offset voltage at power supply switching (VL-VO) of about 8V as an initial target. *6: Please connect ­Pre VCC pin (#5 pin) with the stable minimum voltage and connect so that current does not flow in by reverse bias. *7: Use the standby pin (pin 17) 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 17). *8: Thermal design must be implemented based on the conditions under which the customer's end products are expected to operate on the market. *9: A thermoplastic adhesive resin is used for this hybrid IC.

(VG should desirably be determined by the R14 (VG 0.6V), and current I2 to flows. 3) Latch-up circuit block TR3 is activated when I2 is supplied to the latch-up circuit. When TR3 turns on and current I3 starts flowing, VST goes down to 0V (standby mode), protecting the power amplifier. Since TR3 and TR4 configure a thyristor, once TR3 is activated, the IC is held in the standby mode. To release the standby mode and reactivate the power amplifier, it is necessary to set the standby control voltage (*2) temporarily low (0V). Subsequently, when the standby control is returned to high, the power amplifier will become active again. (*4) The I3 value varies depending on the supply voltage. Determine the value of R2 using the formula below, so that I1 is equal to or less than I3. I1 I3 = VCC/R2 4) DC offset protection block The DC offset protection circuit is activated when ±0.5V (typ) voltage is applied to either "OUT CH1" or "OUT CH2," and the hybrid IC is shut down (standby mode). To release the IC from the standby mode and reactivate the power amplifier, it is necessary to set the standby control voltage temporarily low (0V). Subsequently, when the standby control is returned to high (+5V, for example), the power amplifier will become active again. The protection level must be set using the 82k resistor. Furthermore, the time constant must be determined using 22//22 capacitors to prevent the amplifier from malfunctioning due to the audio signal.
