Texas Instruments OPA2277UA
OPA2277UA variants from Texas Instruments
OPA2277UA Overview
What changes between part numbers, and what to check before you lock the BOM — Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers.
OPA2277UA is a Texas Instruments order-code family — not a single orderable MPN. This page lists 2 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Package: D | Operating Supply Voltage: 18V | Number of Channels: 2 | Max Operating Temp: 85°C | Min Operating Temp: -40°C | Bandwidth: 1MHz Other listed variants describe: 2-Ch Op Amp, 1MHz BW, 50uV Vos, 115dB CMRR, 1.65mA, 18V, 8-SOIC.
Across listed variants, watch these parameters: packages: D.
Example MPNs: OPA2277UA, OPA2277UA/2K5.
Key Features
- Footprint / package: DSingle 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.
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 OPA2277UA 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 |
|---|---|---|---|---|---|---|---|
| OPA2277UA | Package: D | Operating Supply Voltage: 18V | Number of Channels: 2 | Max Operating Temp: 85°C | Min Operating Temp: -40°C | Bandwidth: 1MHz | D | Texas Instruments | Active | Compliant | In Stock | |
| OPA2277UA/2K5 | 2-Ch Op Amp, 1MHz BW, 50uV Vos, 115dB CMRR, 1.65mA, 18V, 8-SOIC | - | Texas Instruments | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on OPA2277UA map to package, grade, and reel options.
OPA2277UA uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 2K5.
Full MPN examples: OPA2277UA/2K5.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right OPA2277UA Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers
Match the footprint first
Packages here: D. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For OPA2277UA, 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 "OPA2277UA" — include the full suffix (e.g. 2K5). RFQ with reel/tube preference and required date code.
