DUAL 150mW AUDIO POWER AMPLIFIER
DESCRIPTION
The UTC PA3112 is a dual audio power amplifier with
differential inputs capable of delivering typically 150mW per
channel of continuous average power to an 16Ω load with less
than 0.1% THD+N using a 5V power supply. The unity-gain stable
UTC PA3112 can be configured by external gain-setting resistors.
The UTC PA3112 features an externally controlled, low-power
consumption shutdown mode. The UTC PA3112 exhibit a low
quiescent current of typically 1.5mA, allowing usage in portable
applications.
