STK4221II - Sanyo

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 signal source resistance causes the output noise to worsen. It is better to decre.

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.
