Near zero pop & click
Lead-free 15 bumps, flip-chip package
Description
The TS4985 has been designed for top-class
stereo audio applications. Thanks to its compact
and power-dissipation efficient flip-chip package,
it suits various applications.
With a BTL configuration, this audio power
amplifier is capable of delivering 1.2W per
channel of continuous RMS output power into an
8
Ω load @ 5V.
Each output channel (left and right), has an
external controlled standby mode pin (STDBYL &
STDBYR) to reduce the supply current to less
than 10nA per channel. The device also features
an internal thermal shutdown protection.
The gain of each channel can be configured by
external gain setting resistors.
Applications
Cellular mobile phones
Notebook & PDA computers
LCD monitors & TVs
Portable audio devices
