Configured as a 1-channel (mono) or 2-channel (stereo) Class AB amplifier, the output type is set by the external feedback network, not a separate variant. ## Package and board integration Housed in a TO-263-10 (9 leads + tab) DDPAK surface-mount package, the exposed thermal tab on the bottom requires a copper land and vias to the ground plane to keep the junction temperature within the -40°C to 85°C operating range at full output. The supplier device package is DDPAK/TO-263-9; the tab is electrically connected to the negative supply rail, so the PCB layout must isolate the tab from other copper unless the rail is shared. ## Supply voltage and protection Operates from a single 9.6 V to 16 V supply — a 12 V automotive rail or a 2-cell Li-ion pack both fit within the range without an extra regulator. Built-in depop circuitry suppresses turn-on/turn-off clicks, and the short-circuit and thermal protection shuts down the output stage before the die exceeds the safe operating area. ## Lifecycle and sourcing Sourced through authorized and independent distribution; pricing and lead time are confirmed at quote against the BOM quantity.","metaTitle":"Texas Instruments LM4950TS Boomer® Class AB Amp, 7.5W","metaDescription":"Texas Instruments LM4950TS Boomer® Class AB audio amplifier, mono 7.5W or stereo 3.1W per channel.
