Op-amps and comparators
General-purpose dual and quad op-amps and open-collector comparators from I-CORE that replace LM358, LM324, RC4558/NJM4558, LM2903 and LM339 in SOP and DIP packages.
| Your part number | I-CORE equivalent | Function | Package | Supply · Temp. |
|---|---|---|---|---|
| LM358DR · LM358DT | AIP358 | Dual operational amplifier | SOP-8 | up to 32 V (±16 V) −40 to 85 °C |
| LM324DR · LM324DT | AIP324 | Quad operational amplifier | SOP-14 | 3–30 V −40 to 85 °C |
| RC4558DR · NJM4558M | AIP4558SA8.TR | Dual operational amplifier (audio) | SOP-8 | See datasheet See datasheet |
| LM2903DR | AIP2903 | Dual differential comparator | SOP-8 | 2–30 V −40 to 125 °C |
| LM339DR | AIP339 | Quad differential comparator | SOP-14 | 2–30 V See datasheet |
How to choose
AIP358 (dual) and AIP324 (quad) are single-supply op-amps whose common-mode range includes ground, for sensor front-ends and DC gain stages up to 30–32 V. AiP4558 is a dual audio op-amp with 3 MHz bandwidth and 8 nV/√Hz noise. AIP2903 (dual) and AIP339 (quad) are comparators with open-collector outputs that can be wired-AND.
Temperature grade
The AiP358 / AiP324 are specified from −40 °C to +85 °C; I-CORE also makes AiP258 / AiP224 variants rated −40 °C to +125 °C; ask about availability.
Reading I-CORE part numbers
| DA / SA / TA | DIP / SOP / TSSOP (e.g. SA16 = SOP-16, TA20 = TSSOP-20) |
|---|---|
| GB235 / GB236 | SOT-23-5 / SOT-23-6 |
| GC353 / GC363 | SOT-353 / SOT-363 (SC-70-5 / SC-70-6) |
| VB / SE / GH223 | SSOP / ESOP (exposed pad) / SOT-223 |
| .TR / .TB | Tape & reel / tube |
Questions buyers ask
- Can AIP358 replace LM358DR directly?
- It uses the standard dual op-amp SOP-8 pinout with a 3–30 V single supply. Check offset and slew-rate requirements against the datasheet.
- Are the comparator outputs open-collector?
- Yes, AIP2903 and AIP339 have open-collector outputs that need a pull-up resistor.
