That 30 W x 2 figure is the maximum output power at 10 % THD+N — for a typical music signal the average power is lower, but the headroom handles transients without clipping into an 8 Ω bookshelf or ceiling speaker. ## Package and thermal — the exposed pad is the heat path The pad carries the heat from the output FETs; without a proper thermal via array under the pad, the junction temperature rises above the 85 °C ambient limit and the thermal protection (one of the listed features) will cycle the output. The differential inputs reject ground noise between the source and the amplifier — useful when the audio source is on a separate board or a remote Bluetooth module. The mute and shutdown pins let a microcontroller hold the outputs off during power-up sequencing to avoid a pop through the speaker. The tape-and-reel packaging suits automated pick-and-place for volume builds. For prototyping or small-batch rework, the cut-tape variant is also listed — specify the exact ordering code suffix when requesting a quote.","metaTitle":"TPA3118D2DAPR Class D amp, 30W x 2 @ 8Ω, 32-HTSSOP","metaDescription":"Active Texas Instruments TPA3118D2DAPR Class D stereo amp, 30W x 2 @ 8Ω, 4.5-26V supply, -40 to 85°C. 32-HTSSOP.
