UNISONIC TECHNOLOGIES CO., LTD PA6112 CMOS IC w w w . u n i s o n i c . c o m . t w 1 of 8 Copyright © 2005 Unisonic Technologies Co., Ltd QW-R502-100,A DUAL 150MW AUDIO POWER AMPLIFIER DESCRIPTION The UTC PA6112 is a dual audio power amplifier with differential inputs capable of delivering typically 150mW per channel of continuous average power to an 16 Ω load with less than 0.1% THD+N using a 5V power supply. The unity-gain stable UTC PA6112 can be configured by external gain-setting resistors. The UTC PA6112 features an externally controlled, low-power consumption shutdown mode. The UTC PA6112 exhibit a low quiescent current of typically 1.5mA, allowing usage in portable applications. FEATURES * Operating voltage range VDD=2.5V~5.5V * Output power: -150mW @5V into 16 Ω * Differential inputs * Shutdown mode available * Low current consumption:3mA max * click and pop reduction circuitry * Unity-gain stable * Thermal and over-current protection MSOP-10 *Pb-free plating product number: PA6112L ORDERING INFORMATION Order Number Normal Lead Free Plating Package Packing PA6112-SM2-R PA6112L-SM2-R MSOP-10 Tape Reel PA6112-SM2-T PA6112L-SM2-T MSOP-10 Tube PA6112 L-SM2-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel, T: Tube (2) SM2: MSOP-10 (3) L: Lead Free Plating , Blank: Pb/Sn
