Frequently Asked Questions
What are the operational requirements for using this audio amplifier?
The TPA2012D2 requires two external components besides power to function.
How does the device protect against electrical surges and heat issues?
It features built-in short-circuit and thermal protection, and a High PSRR of 77 dB at 217 Hz for noise immunity.
Is maximum output power consistent regardless of physical package?
No. The WCSP is thermally limited, meaning the max output power depends on the PCB's ability to dissipate heat.
What selectable gain options are supported by the amplifier?
The user can select gains of 6, 12, 18, or 24 dB using the G0 and G1 pins.
