Supply current, output drive, and the 3 V to 36 V rail
The LM2904BIDR: Each channel draws 300 µA quiescent supply current — low enough for multi-channel boards where the op-amp budget must not dominate the power rail, and the 40 mA per-channel output can drive ADC inputs or small relays directly.
Input offset and bias — the precision floor for a general-purpose part
300 µV maximum input offset voltage and 10 nA input bias current are typical for a general-purpose bipolar op-amp — adequate for 1% signal chains and threshold detection, but not for microvolt-level instrumentation front-ends.
Package and rework: 8-SOIC, surface-mount, tape-and-reel
Supplied in tape-and-reel or cut-tape options, so it feeds into pick-and-place for volume builds or ships as a loose part for prototype benches.
