Description
The TS4994 is an audio power amplifier capable
of delivering 1W of continuous RMS output power
into an 8
Ωload @ 5V. Due to its differential inputs,
it exhibits outstanding noise immunity.
An external standby mode control reduces the
supply current to less than 10nA. An STBY
MODE pin allows the standby to be active HIGH
or LOW. An internal thermal shutdown protection
is also provided, making the device capable of
sustaining short-circuits.
The device is equipped with common mode
feedback circuitry allowing outputs to be always
biased at VCC/2 regardless of the input common
mode voltage.
The TS4994 is designed for high quality audio
applications such as mobile phones and requires
few external components.
Applications
Mobile phones (cellular / cordless)
Laptop / notebook computers
PDAs
Portable audio devices
