Description
Ordering number: EN2322B
Thick Film Hybrid IC
STK4112II AF Power Amplifier (Split Power Supply) (10W + 10W min, THD = 0.
4%)
Features
• The STK4102II series (STK4112II) and STK4101V series (high-grade type) are pin-compatible in the output range of 6W to 50W and enable easy designing.
• Small-sized package whose pin assignment is the same as that of the STK4101II series • Built-in muting circuit to cut off various kinds of pop noise • Greatly reduced heat sink due to substrate temperature 125°C guaranteed • Excellent cost performance
