DESCRIPTION

The TS4890 (MiniSO8 & SO8) is an Audio Power

Amplifier capable of delivering 1W of continuous

RMS. ouput power into 8

Ω load @ 5V.

This Audio Amplifier is exhibiting 0.1% distortion

level (THD) from a 5V supply for a Pout = 250mW

RMS. An external standby mode control reduces

the supply current to less than 10nA. An internal

thermal shutdown protection is also provided.

The TS4890 have been designed for high quality

audio applications such as mobile phones and to

minimize the number of external components.

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

ORDER CODE
