Overview
UNISONIC TECHNOLOGIES CO.
, LTD LM4880 DUAL 250mW AUDIO POWER AMPLIFIER WITH SHUTDOWN MODE  DESCRIPTION The UTC LM4880 is a dual audio power amplifier capable of delivering typically 250mW per channel of continuous average power to an 8Ω load with 0.
1% THD+N using a 5V power supply.
The UTC LM4880 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.
The unity-gain stable UTC LM4880 can be configured by external gain-setting resistors.
 FEATURES * No bootstrap capacitors or snubber circuits are necessary * Unity-gain stable * External gain configuration capability  APPLICATIONS * Personal Computers * CD-ROM Players * Headphone Amplifier  ORDERING INFORMATION Ordering Number Lead Free Halogen Free LM4880L-D08-T LM4880G-D08-T - LM4880G-SH2-R Package DIP-8 HSOP-8 CMOS IC Packing Tube Tape Reel  MARKING DIP-8 www.
