Texas Instruments TPA3144D
TPA3144D variants from Texas Instruments
TPA3144D Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: 2PWP, 2PWPR. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 TPA3144D part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| TPA3144D2PWP | 6-W stereo, 12-W mono, 4.5- to 14.4-V, analog in Class-D audio amplifier w/ inductor free & AGL 28-HTSSOP -40 to 85 | Texas Instruments | Active | Compliant | In Stock | |
| TPA3144D2PWPR | Audio Amp Speaker 1-CH Mono/2-CH Stereo 12W Class-D 28-Pin HTSSOP EP T/R | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right TPA3144D Microcontrollers
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For TPA3144D, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "TPA3144D" — include the full suffix (e.g. 2PWP, 2PWPR). RFQ with reel/tube preference and required date code.
