UTC 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 8Ƹ 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.
