Unisonic Technologies PA3112

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.
