Overview
Ordering number:ENN556F Monolithic Linear IC LA4422 5.
8W typ AF Power Amplifier for Car Stereos, Car Radios Features • High gain (53dB typ.
) and high output (5.
8W typ).
• Soft clip.
• Small number of external parts (4 pcs).
• Bridge construction usable (PO=18W/RL=4Ω).
• Built-in thermal shutdown circuit against load short, overload.
• Built-in circuit to prevent pop noise at the time of power supply ON.
• SIP package (single ended pins) facilitating easy mounting.
