It runs from a 9 V to 32 V supply rail and includes thermal shutdown protection. The operating temperature range is -40 °C to 85 °C, suiting it for industrial or automotive cabin audio where the ambient can climb. Packaged in a DDPAK/TO-263-7 surface-mount case with a tab for heatsinking, it fits designs where board space is tight and a single supply is preferred over split rails. ## 11 W into 4 Ω — what that means for speaker selection The 11 W rating into 4 Ω is the maximum continuous output per channel before clipping. ## Mounting and thermal management The DDPAK/TO-263-7 package has a large exposed tab on the bottom that must be soldered to a copper plane for heatsinking. Without a thermal pad under the tab, the 11 W output will trigger the thermal shutdown at high ambient. The tab is the ground path for the output stage, so the PCB layout should connect it to a low-thermal-resistance ground plane. The seven leads carry the supply, inputs, outputs, and shutdown control — verify the pinout against the datasheet before laying out the board.","metaTitle":"LM4752TS/NOPB Class AB Audio Amp, 11W x 2 @ 4Ω, DDPAK-7","metaDescription":"LM4752TS/NOPB Class AB stereo amplifier, 11W per channel into 4Ω, 9V-32V supply, -40°C to 85°C, thermal shutdown.
