Ratings that matter for the BOM decision
The 10 MHz GBW and 10 V/µs slew rate are the headline specs — they tell you this op-amp handles signal conditioning up to a few MHz without rolling off, which is typical for sensor buffers, active filters, and ADC drivers. The 200 µV input offset and 8 pA input bias are low enough that you don't need to trim or add guard rings in most industrial signal chains. Rail-to-rail output means you get the full 4.5 V to 36 V swing into the load, not a volt or two short of the rails — important when you are trying to maximize ADC dynamic range on a single supply.
Lifecycle and sourcing posture
The OPA2172IDR carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect, so you can qualify it into a production BOM without worrying about a near-term phase-out. Availability is confirmed at quote time through independent distribution — we source and quote to order against an RFQ, with current pricing confirmed when you request it.
