STK4221II AF Power Amplifier

of External Parts C3, C4 Input ﬁlter capacitors * A ﬁlter formed with R5 or R6 can be used to reduce noise at high frequencies. Input coupling capacitors * Used to block DC current. When the reactance of the capacitor increases at low frequencies, the dependence of 1/f noise on signa.

STK4221II Features

* Built-in muting circuit to cut off various kinds of pop noise

* Current mirror circuit application reduces distortion to 0.4% (THD)

* The STK4201II series (THD=0.4%), STK4201V series (THD=0.08%), and STK4141X series (THD=0.02%) are pin-compatible. Package Dimensions unit:
