Texas Instruments INA819IDRG
INA819IDRG variants from Texas Instruments
INA819IDRG Overview
What changes between part numbers, and what to check before you lock the BOM — Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers.
Key Features
- Footprint / package: 8-WFDFN Exposed PadSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: R, T. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers — 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 INA819IDRG part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| INA819IDRGR | Package: 8-WFDFN Exposed Pad | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C (TA) | Current Supply: 350µA | Supplier Device Package: 8-SON (3x3) | Number of Circuits: 1 | 8-WFDFN Exposed Pad | Texas Instruments | Active | Compliant | In Stock | |
| INA819IDRGT | Package: 8-WFDFN Exposed Pad | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C (TA) | Current Supply: 350µA | Supplier Device Package: 8-SON (3x3) | Number of Circuits: 1 | 8-WFDFN Exposed Pad | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right INA819IDRG Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers
Match the footprint first
Packages here: 8-WFDFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For INA819IDRG, 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 "INA819IDRG" — include the full suffix (e.g. R, T). RFQ with reel/tube preference and required date code.
