What the key specs mean for your BOM line
The OPA2310IDR: Supply current is 165 µA per channel, so the whole dual package draws about 330 µA quiescent — a good fit for battery-powered or loop-powered designs where every microamp counts.
Package and rework considerations
Pin 1 is clearly marked with a dot and a bevel on the package body, so orientation is unambiguous under a microscope.
Texas Instruments lists the OPA2310IDR as Active product status. It is RoHS3 compliant with no known end-of-life notice.
