| UNISONIC TECHNOLOGIES CO., LTD S486 DUAL 100mW AUDIO POWER AMPLIFIER WITH STANDBY MODE DESCRIPTION The UTC S486 is a dual power amplifier capable of delivering typically 100mW per channel of continuous average power to an 8 load with 0.1% THD+N using a 5V power supply. The UTC S486 features an externally controlled, low-power consumption shutdown mode. The UTC S486 exhibit a low quiescent current of typically 1.8mA, allowing usage in portable applications. The unity-gain stable UTC S486 can be configured by external gain-setting resistors. CMOS IC SOP-8 *Pb-free plating product number: S486L FEATURES * Operating voltage range VCC=2V ~ 5.5V * Output power: - 102mW @5V into 16 with 0.1% THD+N max (1kHz) * Shutdown mode available * Low current consumption: 2.5mA max * Click and pop reduction circuitry * Unity-gain stable * Short circuit protected ORDERING INFORMATION Normal S486-S08-R S486-S08-T Order Number Lead Free Plating S486L-S08-R S486L-S08-T Package SOP-8 SOP-8 Packing Tape Reel Tube S486L-S08-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel, T: Tube (2) S08: SOP-8 (3) L: Lead Free Plating, Blank: Pb/Sn www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., Ltd 1 of 12 QW-R107-052,A S486 PIN CONFIGURATION CMOS IC OUT (1) VIN (1) BYPASS GND 1 2 3 4 8 7 6 5 VCC OUT (2) VIN (2) SHUTDOWN UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 12 QW-R107-052,A S486 ABSOLUTE MAXIMUM RATING (Ta=25 ) CMOS IC PARAMETER SYMBOL RATINGS UNIT Supply voltage (Note 2) VCC 6 V Input Voltage VIN -0.3V ~ VCC+0.3V V Output Short-Circuit to VCC or GND Continuous(Note 3) Power Dissipation (TJ=150 ) PD 0.71 W Junction Temperature TJ +150 Operating Temperature TOPR -40 ~ +85 Storage Temperature TSTG -65 ~ +150 Note: 1.Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2.All voltage values are measured with respect to the ground pin. 3.Attention must be paid to continuous power dissipation (VDD x 300mA). Exposure of the IC to a short circuit for an extended time period is dramatically reducing product life expectancy.
