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.
