TS4990JT - FLIP CHIP
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
8Ω 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
