rod DESCRIPTION

P The TS4872 is an Audio Power Amplifier capable

te of delivering 1W of continuous RMS Ouput Power

le into 8Ω load @ 5V.

so This Audio Amplifier is exhibiting 0.1% distortion

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

RMS. An external standby mode control reduces

- O the supply current to less than 10nA. An internal

) shutdown protection is provided.

t(s The TS4872 has been designed for high quality

c audio applications such as mobile phones and to

u minimize the number of external components.

rod The unity-gain stable amplifier can be configured

by external gain setting resistors.

te P APPLICATIONS

le ■ Mobile Phones (Cellular / Cordless)

o ■ PDAs

bs■ Laptop/Notebook computers

O■ Portable Audio Devices
