Frequently Asked Questions
What is the continuous stereo output power?
The TPA112 provides a wide range of supply voltages capable of delivering 150 mW of continuous RMS power per channel.
What are the operating voltage constraints?
It can operate from 2.5 V to 5.5 V, and the recommended supply voltage is between 2.5 V and 5.5 V.
How is total harmonic distortion influenced by load impedance?
For 32-Ω loads, the THD+N performance of the device is reduced compared to an 8-Ω load.
Does the amplifier have built-in protection features?
It includes thermal and short-circuit protection on both input channels.
