DESCRIPTION

The TS482 is a dual audio power amplifier able to

drive a 16 or 32

Ω stereo headset down to low volt-

ages.

It’s delivering up to 100mW per channel (into 16

Ω

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

s Stereo Headphone Amplifier

s Optical Storage

s Computer Motherboard

s PDA, organizers & Notebook computers

s High end TV, Set Top Box, DVD Players

s Sound Cards

ORDER CODE
