3-W STEREO AUDIO POWER
AMPLIFIER WITH ADVANCED
DC VOLUME CONTROL
DESCRIPTION
As a stereo audio speaker which is operating on a single
5.5V supply, the UTC PA3011 is capable of delivering 3W of
output power per channel into 3Ω loads with less than 10%
THD+N.
The speaker volume level is adjusted by applying a dc
voltage to the VOLUME terminal. When a dc voltage is applied, to
avoid an unexpected high volume level through the headphones,
a third terminal, SEMAX, limits the headphone volume level. And
also a fade mode ramps the volume up and down to ensure a
smooth transition between active and shutdown modes,.
The UTC PA3011 can be applicatated in notebook, LCD
monitors and pocket PC.
Lead-free:
Halogen-free: PA3011G
PA3011L
FEATURES
* DC volume control with 2-dB steps :-40 dB ~ 20 dB
* Fade mode
* Maximum volume setting for SE mode
* 3 W into 3ꢀ load
* MUX stereo input
