PA4990 Datasheet | Unisonic Technologies

DESCRIPTION As a power amplifier which is operating on a single 5V supply, the UTC PA4990 is capable of delivering 1.2W of output power into 8Ω loads with less than 1% distortion. The UTC PA4990 is optimally suited for applications: Mobile phones (cellular/cordless), notebook puters PDAs and Portable audio devices. The shutdown mode can reduce the supply current to less than 10n A. It also includes thermal shutdown protection internally. By external gain setting resistors the gain can be configured. - FEATURES - Operating: VCC=2.2V ~ 5.5V - 1.2W output power, VCC=5V, THD=1%, f=1k Hz, 8Ω Load - In shutdown mode: Ultra-low consumption (10n A) - In grounded mode: 62d B PSRR @ 217Hz - POP & CLICK near-zero - Ultra-low distortion :0.1% (typ) - ORDERING INFORMATION Ordering Number Lead Free Halogen Free PA4990L-S08-R PA4990G-S08-R PA4990L-SM2-R PA4990G-SM2-R Package SOP-8 MSOP-8 CMOS IC Packing Tape Reel Tape Reel - MARKING .unisonic..tw Copyright © 2018 Unisonic Technologies Co., Ltd 1 of 9 QW-R502-235.G - PIN CONFIGURATION CMOS IC - PIN DESCRIPTION PIN NO 2 3 4 5 6 7 8 PIN NAME SHUTDOWN BYPASS +IN -IN VOUT1 VDD GND VOUT2 DESCRIPTION Shutdown control input...
