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. 4700 µF 4700 µF DBA30C 500 Ω 500 Ω +VCC --VCC + + Designated Transformer Power Supply (RP-25 equivalent) Parameter Symbol Conditions Ratings Unit Maximum supply voltage (No signal) VCC max(0) ±36 V Maximum supply voltage VCC max(1) RL ≥ 6 Ω ±34 V Minimum operating supply voltage VCC min ±10 V Maximum operation flow-in current (pin 23) IST OFF max 1.2 mA Thermal resistance θ j-c Per power transistor 3.6 °C/W Junction temperature Tj max Both the Tj max and the Tc max conditions must be met. 150 °C Operating IC substrate temperature Tc max 125 °C Storage temperature Tstg –30 to +125 °C Allowable load shorted time *4 ts VCC = ±23.0 V, RL = 6 Ω, f = 50 Hz, PO = 20 W, 1ch drive 0.3 s Parameter Symbol Conditions*1 Ratings Unit VCC (V) f (Hz) PO (W) THD (%) min typ max PO (1) ±23.0 20 to 20 k 0.6 18 20 Output power *1 PO (2) ±23.0 1 k 10 30 W THD (1) ±23.0 20 to 20 k 5.0 VG = 30 dB 0.6 Total harmonic distortion *1 THD (2) ±23.0 1 k 5.0 VG = 30 dB 0.03 % Frequency characteristics fL, fH ±23.0 1.0 +0 –3 dB 20 to 50 k Hz Input impedance ri ±23.0 1 k 1.0 55 k Ω Output noise voltage *2 VNO ±28.0 Rg = 2.2 k Ω 1.0 mVrms Quiescent current ICCO ±28.0 No loading 60 110 180 mA Neutral voltage VN ±28.0 –70 0 +70 mV Current flowing into pin 23 IST ON ±23.0 V23 = 5 V, current Limiting 0 mA in standby mode *6 resistance: 6.2 k Ω Current flowing into pin 23 IST OFF ±23.0 0.4 1.2 mA in operating mode *6 |
