 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.
