At 4Ω the amplifier hits its rated 6.7W maximum; into 8Ω the output drops proportionally, but the Class D efficiency (typically >85% at moderate power) keeps heatsinking minimal. The differential inputs reject ground noise common in single-supply layouts, and the depop feature suppresses the turn-on thump that otherwise needs an external mute circuit. ## Protection set for production robustness Short-circuit and thermal protection are integrated, so a speaker-wire short or a stalled fan in an enclosure won't cascade into a board-level failure. The shutdown pin lets a system controller put the amplifier into a low-power idle — useful for power-conscious designs where the amp is off when no audio is playing. ## Lifecycle and compliance The \"NOPB\" suffix confirms lead-free / RoHS3 — no separate waiver or special handling needed for EU or California markets.","metaTitle":"LM48511SQX/NOPB Class D Audio Amplifier, 6.7W Mono, 24-WQFN","metaDescription":"Texas Instruments LM48511SQX/NOPB Boomer® Class D audio amp, 6.7W into 4Ω mono, 3V-5.5V supply, -40°C to 85°C, 24-WQFN.
