DESCRIPTION
The TS4890 (MiniSO8 & SO8) is an Audio Power
Amplifier capable of delivering 1W of continuous
RMS. ouput power into 8
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
