At 8Ω the output stage runs cooler than a 4Ω load at the same power, so the exposed pad on the 32-VFQFN package can dissipate the heat into a copper plane without a forced-air fan in many designs. ## Supply range and system power rail selection The 8V to 26V supply range means this amplifier can run from a single-cell lithium-ion battery (nominal 3.7V boosted to 8V) all the way up to a regulated 24V industrial supply. The 26V upper limit covers the tolerance on a 24V rail without needing an external clamp — a common requirement for audio in factory-floor announcement systems or outdoor paging units. ## SpeakerGuard™ protection — what it saves on the BOM The integrated SpeakerGuard™ depop circuit eliminates the power-on pop that otherwise requires an external muting relay or a dedicated soft-start circuit. Short-circuit and thermal protection are built in — the amplifier shuts down before the output FETs overheat, which removes the need for a separate thermal switch or PTC resettable fuse on the speaker line. The differential inputs reject ground noise between the source and the amplifier, saving a ground-lift resistor or isolation transformer in a multi-device setup. ## Active lifecycle and sourcing The part is ROHS3 compliant, which means no RoHS exemption expiry to track for EU or California shipments.","metaTitle":"Texas Instruments TPA3117D2RHBR Class D Amp, 15W x 2","metaDescription":"Texas Instruments TPA3117D2RHBR Class D stereo amplifier, 15W x 2 into 8Ω, 8V-26V supply, SpeakerGuard™ protection.
