... All of the above assume no ambient airflow. The stereo output controller is available in either an LX1722 high power version (>65Wrms, 4Ω) with a supply voltage range of 7V-25V or an LX1721 high fidelity version (better SNR performance) with a supply voltage range of 7V-15V. The current rating of the external MOSFET’ ...
