1 / 7 page UNISONIC TECHNOLOGIES CO., LTD PA4867 CMOS IC www.unisonic.com.tw 1 of 7 Copyright © 2011 Unisonic Technologies Co., Ltd QW-R502-125.B DUAL 2.1W AUDIO AMPLIFIER PLUS STEREO HEADPHONE FUNCTION DESCRIPTION The UTC PA4867 is a stereo audio power amplifier capable of delivering typically 2.1W to a 4Ω load or 2.4W to a 3Ω load each channel with less than 1.0% THD+N using a 5V power supply. UTC PA4867 has a new circuit topolopy which can eliminate headphone output coupling capacitors. And an internal input MUX allows two sets of stereo inputs to the amplifier. The UTC PA4867 has integrated depop circuitry that virtually eliminates transients that cause noise in the speakers during power up and when using the shutdown modes. FEATURES * Operating voltage range VDD=2V~5.5V * Output power: -2.4W(typ.)@5V into 3Ω with 1% THD+N max (1kHz) -2.1W(typ.)@5V into 4Ω with 1% THD+N max (1kHz) * Eliminates SE-mode output coupling capacitors * Shutdown mode available * click and pop reduction circuitry * Unity-gain stable * Thermal-shutdown Protection * Input MUX control * SE/BTL mode available ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing PA4867L-N20-R PA4867G-N20-R HTSSOP-20 Tape Reel PA4867L-N20-T PA4867G-N20-T HTSSOP-20 Tube PA4867L-P20-R PA4867G-P20-R TSSOP-20 Tape Reel PA4867L-P20-T PA4867G-P20-T TSSOP-20 Tube |
