TPA3116D2DAD

TPA3116D2DAD is the tube order code of Texas Instruments’ TPA3116D2 50-W stereo Class-D audio amplifier in 32-pin HTSSOP — for powered speakers, soundbars and aftermarket automotive audio: 2x50 W into 4 ohms at 21 V (10% THD+N), a rating TI specifies with a small heatsink attached to the top-side PowerPAD, 4.5-V to 26-V supply range, over 90% efficiency with low idle loss. The feedback power-stage architecture delivers high PSRR so the power supply can be simpler and cheaper, while AM-avoidance switching frequencies (up to 1.2 MHz, master/slave sync) keep multi-amp systems clean. Selection advice: this is the 50-W member of the TPA31xxD2 family sharing one footprint — for 30-W designs the TPA3118D2 and for 15-W the TPA3130D2 sit in the same datasheet family. Order-code discipline matters: the TPA3116D2 is orderable only in the pad-up DAD package — DAD in tube (this code) and DADR on tape and reel; the pad-down DAP package belongs to the TPA3118D2/TPA3130D2 and there is no TPA3116D2 DAP orderable. Programmable power limit and full fault reporting (overvoltage, overtemperature, DC-detect, short-circuit) suit unattended commercial installs.
