AN7173K

The AN7173K is designed as the integrated circuit for 14W output power amplifier. Stereo operation is enables due to incorporating two BTL amplifiers in one chip. High reliability is obtained due to incorporating various protectors. ON/OFF is enabled even if power is supplied to power supply pin by incorporating standby circuit.

AN7173K has six features. (1)High output power. (2)Incorporating standby circuits. (3)Incorporating protection circuits (temperature, overvoltage, Vout-GND short, load short, Vout-Vcc short). (4)Low shock noise from power ON/OFF operation. (5)Fewer external components. (6)Highly stable operation. Those are all the main features.

Some absolute maximum ratings of AN7173K have been concluded into several points as follow. (1)Its supply voltage would be 24V. (2)Its peak supply voltage would be 50V. (3)Its supply current would be 6.0A. (4)Its power dissipation would be 62.5W. (5)Its operating ambient temperature range would be from -30°C to +75°C. (6)Its storage temperature range would be from -55°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some AN7173K electrical characteristics are concluded as follow. (1)Its quiescent circuit current would be typ 120mA and max 200mA. (2)Its output noise voltage would be typ 0.6mV and max 1.5mV. (3)Its voltage gain would be min 50.5dB and typ 52.5dB and max 54,5dB. (4)Its total harmonic distortion would be typ 0.2% and max 0.75%. (5)Its maximum output power is min 9.0W and typ 12.5W. (6)Its ripple rejection ratio would be min 35dB and typ 40dB. (7)Its total harmonic distortion at 100Hz would be typ 0.25%. (8)Its total harmonic distortion at 10KHz would be typ 0.45%. (9)Its frequency characteristics would be typ 22KHz for high and would be typ 21Hz for low. And so on.
