TPA3116D2 is a Texas Instruments 50-W stereo Class-D audio amplifier in 32-pin HTSSOP — for powered speakers, soundbars and aftermarket automotive audio where high output must come without a heatsink: 2x50 W into 4 ohms at 21 V, 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 on this site drops into the same PCB, and for 15-W the TPA3130D2; the DAD suffix is the pad-up HTSSOP, DAP the pad-down. Programmable power limit and full fault reporting (overvoltage, overtemperature, DC-detect, short-circuit) suit unattended commercial installs. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
TPA3116D2 is a Audio power amplifier from Texas Instruments, orderable in the HTSSOP-32 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.
When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. TPA3116D2 names the HTSSOP-32 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.
The package (HTSSOP-32) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.
Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.
Add TPA3116D2 to your RFQ with the complete ordering code, the manufacturer (Texas Instruments), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
