Power Amplifier for 3V Headphone Stereos

SANYO -> Panasonic 

Ordering number:ENN2248B

Monolithic Linear IC

LA4533M

Power Amplifier for 3V Headphone Stereos

Features

• Low current consumption.

• 16Ω load drive capability.

• Excellent reduced voltage characteristics.

• Excellent power supply ripple rejection.

• Minimum number of external parts required (no input

capacitor, feedback capacitor required).

• Applicable to radio sets because of high voltage gain.

• Less harmonic interference in radio band.

• On-chip power switch function, muting function.
