Sure thing. This is 540mW and looking at https://electronics.stackexchange.com/a/36495/27147 https://electronics.stackexchange.com/a/36495/27147 > headphone jacks typically provide only 10-20 mW of output power. microphones draw even less. A handful of mW is plenty to drive even an ARM Cortex M0 not that you need something that complex.
