1 / 11 page  UNISONIC TECHNOLOGIES CO., LTD PA3202 CMOS IC www.unisonic.com.tw 1 of 11 Copyright © 2009 Unisonic Technologies Co., Ltd QW-R502-106.C 2-W STEREO AUDIO POWER AMPLIFIER WITH MUTE DESCRIPTION The UTC PA3202 is a monolithic integrated circuit that stereo bridged audio power amplifiers capable of producing 2 W into 3Ω with a 5V supply voltage or 800mW into 3Ω with a 3.3V supply voltage .The UTC PA3202 simplifies design and frees up board space for other features. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in UTC PA3202, that reduce clicks and pops noise during power up or shutdown mode operation. A MUX control terminal ) LINE / HP ( allows selection between the two sets of stereo input signals. To simplify the audio system design, UTC PA3202 combines a stereo bridge-tied loads (BTL) mode for speaker drive and a stereo single-end (SE) mode for headphone drive into a single chip, where both modes are easily switched by the BTL / SE input control pin signal. FEATURES * Improves depop circuitry to eliminate turn-on and turn-off transients in output * Output power: -2W(typ.)@5V into 3Ω with 0.2% THD+N max (1kHz) -800mW(typ.)@3.3V into 3Ω with 0.2% THD+N max (1kHz) * Fully specified for use with 3-Ω Loads * Stereo switchable bridged/single-ended power amplifiers * Input MUX select terminal * Thermal-shutdown protection * Shutdown mode available HTSSOP-24 ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing PA3202L-N24-R PA3202G-N24-R HTSSOP-24 Tape Reel PA3202L-N24-T PA3202G-N24-T HTSSOP-24 Tube |
