Product details

Quad op-amp in a hermetic CDIP — what you're getting

The Texas Instruments LM124AJ/PB is a quad general-purpose operational amplifier from the LinCMOS™ series, packaged in a 14-CDIP (0.300", 7.62 mm) ceramic dual-in-line with through-hole mounting. Four independent amplifiers in one package, each with a 1 MHz gain-bandwidth product and 40 mA output current capability. Supply range spans 3 V to 32 V, drawing 1.5 mA total quiescent current. Input offset voltage is 2 mV typical, input bias current 45 nA. The -55 °C to 125 °C junction temperature range puts this squarely in the military / high-reliability tier — avionics, satellite, downhole instrumentation, or any sealed-environment board where a plastic SOIC won't cut it. The ceramic DIP handles thermal cycling and moisture resistance that plastic packages can't match.

Supply voltage range — why it simplifies the BOM

Supply span is 3 V to 32 V.

14-CDIP package — rework and handling notes

The 14-CDIP (0.300" body width, 7.62 mm row spacing) is a through-hole ceramic package.

Active lifecycle — no LTB risk for new designs

Product status is Active per the manufacturer. No last-time-buy notice, no end-of-life flag. This part can be specified into new production builds with confidence. ROHS3 compliant — no lead-free conversion concern for legacy Pb-free assembly lines.

Frequently asked questions

Is LM124AJ/PB a direct replacement for LM124N?

The LM124AJ/PB and LM124N are both quad general-purpose op-amps from TI with the same 1 MHz GBP, 3-32 V supply, and -55 to 125 °C range. The key difference is the package: LM124AJ/PB is a 14-CDIP (ceramic DIP), while LM124N is typically a plastic PDIP. They are pin-compatible in function and pinout, but the ceramic package is specified for hermetic / high-reliability environments. If your board originally used a plastic DIP and the environment doesn't require hermetic sealing, the LM124N is the direct drop-in. If the board was designed for a ceramic DIP socket, the LM124AJ/PB is the correct fi

Is LM124AJ/PB obsolete or EOL?

No. The product status is Active per the manufacturer. There is no end-of-life notice or last-time-buy schedule in effect.

Does LM124AJ/PB have a RoHS or lead-free variant?

Yes, the LM124AJ/PB is ROHS3 Compliant. No separate lead-free variant is needed — this part already meets the ROHS3 directive.

When sourcing LM124AJ/PB, what's the closest functional second-source?

The INA4290A2IRGVR is a quad current-sense amplifier with a 1.1 MHz bandwidth and 2 V/µs slew rate, but it is a current-sense type, not a general-purpose op-amp, and it runs on a 2.7 V supply in a surface-mount package. It is not a pin-compatible or functional replacement for the LM124AJ/PB. For a general-purpose quad op-amp in a similar performance class, the TLV9352IDDFR (dual, 10.6 MHz) or TLV9351IDCKR (single, 3.5 MHz) are newer CMOS alternatives but in surface-mount packages and with fewer channels per package. No exact second-source exists in a 14-CDIP package with the same quad configur
