Its key differentiator is a 0.45 µV input offset voltage — low enough to eliminate the need for external offset trimming in most precision DC measurement circuits. With a 5 MHz gain-bandwidth product and 10 V/µs slew rate, this part handles sensor conditioning, bridge amplifiers, and data-acquisition front-ends that require both DC accuracy and moderate bandwidth. Operating temperature is -40°C to 125°C.
Yes, the OPA2182ID has a rail-to-rail output stage, allowing the output to swing close to both supply rails.
No official cross-reference is listed. The TLV9351IDCKR (single, 3.5 MHz, general-purpose) and TLV9362IDDFR (dual, 10.6 MHz, general-purpose) are functional alternatives if zero-drift performance is not required — they share the same 8-SOIC footprint and rail-to-rail output.
