Product details

50W per channel — what that means for the speaker load

The TPA3116D2DADR is a Class-D stereo amplifier from TI's SpeakerGuard™ series. It delivers 50W per channel into a 4Ω load from a single supply rail spanning 4.5V to 26V. Built-in short-circuit and thermal protection plus a dedicated mute pin simplify the system-level protection scheme. Differential inputs reject ground-loop noise common in multi-channel installations. The 32-HTSSOP package with exposed pad draws heat to the PCB copper plane — no external heatsink needed for typical music playback at moderate levels.

Supply voltage and temperature — fit for your environment

Rated for -40°C to 85°C ambient, this part covers industrial enclosures, outdoor telecom cabinets, and automotive cabin installations.

Frequently asked questions

What is the output power rating of TPA3116D2DADR per channel?

50W per channel into a 4Ω load, measured at the maximum output before clipping. That's the 2-channel (stereo) configuration driving a 4Ω speaker on each channel.

Is TPA3116D2DADR obsolete or active?

Active. Texas Instruments lists it as current production with no end-of-life notice. ROHS3 compliant.

Is TPA3116D2DADR compatible with single supply operation?

Yes, it operates from a single supply rail between 4.5V and 26V. No negative rail needed.

What is the difference between TPA3116D2 and TPA3116D2DADR?

The TPA3116D2DADR is the tape-and-reel packaged variant of the TPA3116D2. The die and electrical specifications are identical. The 'DADR' suffix indicates the 32-HTSSOP package in tape-and-reel format.
