Description
The TS482 is a dual audio power amplifier able to
drive a 16 or 32
stereo headset down to low
voltages.
It is delivering up to 100mW per channel (into 16
loads) of continuous average power with 0.1%
THD+N from a 5V power supply.
The unity gain stable TS482 can be configured by
external gain-setting resistors.
Applications
■ Stereo headphone amplifier
■ Optical storage
■ Computer motherboard
■ PDA, organizers & notebook computers
■ High-end TV, set-top box, DVD players
■ Sound cards
