Power supply current rating required
Continuous output power, P
Audio input voltage, V
Minimum load impedance, Z
Note:
The TPA2012D2 in the RTJ package (QFN) is rated at 2.1 W/channel. The YZH package
(WCSP) is thermally limited to 1.2 W/channel on the EVM. For layouts with higher trace
density and additional copper, the maximum output power will be larger. See the data
sheet for device descriptions.
