Description
The TS4972 is an Audio Power Amplifier capable
of delivering 1.6W of continuous RMS ouput
power into a 4
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
shutdown protection is provided.
The TS4972 has 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
■ Mobile phones (cellular / cordless)
■ PDAs
■ Laptop/notebook computers
■ Portable audio devices
