Series Organization
Specifications
Maximum Ratings at Ta = 25°C
These products are organized as a series based on their output capacity.
Operating Characteristics at Tc = 25°C, RL = 6 Ω (noninductive load), Rg = 600 Ω, VG = 30 dB
Notes: 1. 1ch drive
2. Unless otherwise noted, use a constant-voltage supply for the power supply used during inspection.
3. Use the transformer power supply circuit shown in the figure below for allowable load shorted time measurement and output noise voltage
measurement.
4. The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50 Hz) power supply should be used to
minimize the influence of AC primary side flicker noise on the reading.
5. Design applications so that the minus pre-VCC line (pin 17) is the lowest potential applied to the IC at all times.
6. A limiting resistor that assures that the maximum operating current flowing into the standby pin (pin 23) does not exceed the maximum rating must
be included in application circuits. This IC operates when a voltage higher than VBE (about 0.6 V) is applied to the standby pin.
