Texas Instruments TPA2005D
TPA2005D variants from Texas Instruments
TPA2005D 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.
- 4 distinct suffix patternsExamples: 1DGNG4, 1DGNR, 1DRBR, 1EVM. 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 4 TPA2005D 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 |
|---|---|---|---|---|---|---|
| TPA2005D1DGNG4 | 1.4-W Mono Class-D Audio Amplifier (TPA2005) 8-HVSSOP -40 to 85 | Texas Instruments | Active | Compliant | In Stock | |
| TPA2005D1DGNR | 1.4W Mono Class-D Audio Amp, 2.5-5.5V, 8R, HTSSOP EP | Texas Instruments | Active | Compliant | In Stock | |
| TPA2005D1DRBR | 1-CH Class-D Audio Amp, 1.45W, 8R, 2.5-5.5V, SON | Texas Instruments | Active | Compliant | In Stock | |
| TPA2005D1EVM | Audio IC Development Tools TPA2005D1 Eval Mod | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right TPA2005D 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 TPA2005D, 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 "TPA2005D" — include the full suffix (e.g. 1DGNG4, 1DGNR, 1DRBR). RFQ with reel/tube preference and required date code.
