STK3042II

The STK3042II is designed as a voltage amplifier for 40 to 50 watt AF power amplifier.

Some absolute maximum ratings of STK3042II at Ta=25°C have been concluded into several points as follow. (1) Uts maximum supply voltage would be +/- 55V. (2) Its allowable power dissipation would be max 4 watt. (3) Its operatig case temperature would be 100 °C. (4) Its storage temperature would have the minimum value of -30 °C and the maximum value of +100°C. That are all the main maximum ratings and it should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some recommended operating conditions at Ta= 25°C have been concluded into several points as follow. (1) Its recommended supply voltage would be +/- 43 volts. (2) Its load resistance would be 33K ohms. That are all the recommended operating conditions.

And also some operating characteristics of STK3042II at Ta=25°C, VG=26.5 dB, RL=22K ohms (unless otherwise specified) have been concluded into several points as follow. (1) Its current dissipation which has the symbol of Icc would have the maximum value of 30 mA. (2) Its output center voltage which has the symbol of Vn would have the minimum value of -50 mV and the maximum value of +50 mV. (3) Its output noise voltage  which has the symbol of Vno would have the maximum value of 1.0 mV. (4) Its input resistance which has the symbol of ri would be 33K ohms. (5) Its total harmonic distortion which has symbol of THD would have the maximum value of 0.01%. That are all the main characteristics. And so on.

At present we have not got so much information about STK3042II and we would try hard to get more information. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
