The LM2904DGK: Supply range spans 3 V to 26 V.
The 20 nA input bias current and 3 mV input offset voltage are typical for this class; designs that need tighter DC accuracy should budget for an external trim or select a precision-grade sibling.
Buyers supporting long-life industrial or medical equipment should qualify a pin-compatible drop-in while supply lasts.
A pin-compatible alternative within the LM2904 family (e.g., LM2904DR in SOIC-8) may serve as a form-fit-function substitute, but the package differs — the DGK suffix indicates the 8-VSSOP footprint. Confirm the board layout and supply voltage range before substituting.
The LM2904 is the base device family; the DGK suffix specifies the 8-VSSOP package (3.00 mm width) and the tape-and-reel / cut-tape shipping format. Electrically, the LM2904DGK shares the same 700 kHz GBW, 0.3 V/µs slew rate, and 3 V to 26 V supply range as other LM2904 variants. The difference is purely mechanical — footprint and handling.
If your application stays within 0°C to 70°C and the supply voltage (3 V to 32 V for LM358) is compatible, the LM358 can be a functional substitute. For extended-temperature environments, the LM2904DGK is the correct choice.
