s OPERATING FROM V

CC = 2.2V to 5.5V

s 1W OUTPUT POWER @ Vcc=5V, THD=1%,

f=1kHz, with 8

Ω Load

s ULTRA LOW CONSUMPTION IN STANDBY

MODE (10nA)

s 62dB PSRR @ 217Hz @ Grounded mode

s Zero POP & CLICK

s ULTRA LOW DISTORTION (0.1%)

s UNITY GAIN STABLE

s AVAILABLE IN 9 BUMPS Flip Chip Package

DESCRIPTION

The TS4990 has been designed for demanding

audio applications such as mobile phones and to

minimize the number of external components.

This Audio Power Amplifier is capable of deliver-

ing 1W of continuous RMS Ouput Power into an

8

Ω load @ 5V.

An externally controlled standby mode control re-

duces the supply current to less than 10nA. It also

includes an internal thermal shutdown protection.

The unity-gain stable amplifier can be configured

by external gain setting resistors.

APPLICATIONS

s Mobile Phones (Cellular / Cordless)

s Laptop / Notebook Computers

s PDAs

s Portable Audio Devices
