1 / 7 page UNISONIC TECHNOLOGIES CO., LTD PA301 1 CMOS IC www.unisonic.com.tw 1 of 7 Copyright © 2008 Unisonic Technologies Co., Ltd QW-R502-247.A 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. FEATURES * DC volume control with 2-dB steps :-40 dB ~ 20 dB * Fade mode * Maximum volume setting for SE mode * 3 W into 3Ω load * MUX stereo input Lead-free: PA3011L Halogen-free: PA3011G ORDERING INFORMATION Ordering Number Normal Lead Free Plating Halogen Free Package Packing PA3011-N24-R PA3011L-N24-R PA3011G-N24-R HTSSOP-24 Tape Reel PA3011-N24-T PA3011L-N24-T PA3011G-N24-T HTSSOP-24 Tube |
