Operating Characteristics at Ta = 25°C, RL = 6 Ω, Rg = 600 Ω, VG = 40 dB, RL (noninductive)

Internal Equivalent Circuit

Notes

• Use rated power supply for testing unless otherwise specified.

• When measuring permissible load short time and output noise voltage, use transformer power supply indicated below.

• Output noise voltage is represented by the peak value rms (VTVM) for mean reading. Use an AC stabilized power

supply (50 Hz) on the primary side to eliminate the effect of AC flicker noise.
