TS482

100mW Stereo Headphone Amplifier

■ Operating from Vcc=2V to 5.5V

■ 100mW into 16

Ω at 5V

■

38mW into 16

Ω at 3.3V

■ 11.5mW into 16

Ω at 2V

■ Switch ON/OFF click reduction circuitry

■ High power supply rejection ratio: 85dB at 5V

■ High signal-to-noise ratio: 110dB(A) at 5V

■ High crosstalk immunity: 100dB (F=1kHz)

■ Rail-to-rail input and output

■ Unity-gain stable

■ Available in SO-8, MiniSO-8 & DFN8

Description

The TS482 is a dual audio power amplifier able to

drive a 16 or 32

Ω stereo headset down to low

voltages.

It is 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

■ Stereo headphone amplifier

■ Optical storage

■ Computer motherboard

■ PDA, organizers & notebook computers

■ High-end TV, set-top box, DVD players

■ Sound cards
