STK442-090 2000.04.18
1. Case Outline 14Pins (See attached outline drawing)
2. Function class AB 2 channels AF power amplifier
3. Application 50W audio use
4. Maximum Ratings / Ta=25deg
5. Operating Characteristics
Tc=25deg,RL =6ohm(Non-inductive Load),Rg=600ohm,VG=30dB
*Specifications and information herein are subject to change without notice.
Note *1.1ch Drive
*2.All tests are measured using a constant-voltage supply unless otherwise specified.
*3.The output noise voltage is peak value of an average-reading meter with a rms value scale(VTVM).
A regulated AC supply(50Hz) should be used to eliminate the effects of AC primary line flicker
noise.
*4.Available time for load short-circuit and output noise voltage are measured using the specified
transformer power supply.
