Ordering number : EN4585A
Thick Film Hybrid IC
STK4211V
2-Channel 70 W min AF Power Amplifier (Split Power Supply)
Features
* The inclusion of a muting circuit on-chip allows all types of impulse noise to be excluded. * Current mirror circuit application reduces distortion to 0.008%. * Pin compatible with the STK4201II Series (THD = 0.4%) and the STK4141X Series (THD = 0.02%)
