The system must provide a regulated 1.8V rail (typical) that can source the peak current during the 2W burst. I²C control handles volume, mute, and shutdown — no analog potentiometers or external gain-setting resistors are needed. The shutdown feature lets the host put the amplifier into a low-power state when audio is idle. ## Package and thermal — board integration checklist 24-VFQFN with exposed pad (4x4 mm body per the supplier device package). Surface-mount assembly with a standard lead-free reflow profile; the exposed pad requires a solder paste stencil aperture that covers at least 50% of the pad area for reliable void-free attachment. ## Temperature grade and operating environment The junction temperature will rise above ambient under load, so the thermal pad design must keep Tj below the 125°C absolute maximum.","metaTitle":"TAS2505IRGER Class D Mono Amp, 2W into 4Ω, 24-VQFN","metaDescription":"Texas Instruments TAS2505IRGER Class D audio amplifier, 2W mono into 4Ω with headphone channel.
