Product details

Quad general-purpose op-amp in the legacy 14-DIP footprint

The MC3403N is a quad general-purpose operational amplifier from Texas Instruments, packaged in a 14-lead DIP (0.300" body) for through-hole assembly.

Rated for 5 V minimum to 30 V maximum supply span, this part covers the common industrial and instrumentation rails. The 2.8 mA total quiescent current (all four channels) keeps the power budget modest in multi-channel boards.

Input offset and bias — DC precision for non-critical paths

Typical input offset voltage is 2 mV, and input bias current is 200 nA. These figures place the MC3403N in the workhorse category — fine for summing amplifiers, active filters with moderate gain, and comparator duties where a few millivolts of offset are acceptable. For precision instrumentation or microvolt-level sensing, a lower-offset part (e.g., OPAx series) would be a better fit.

Active lifecycle — no near-term obsolescence

Frequently asked questions

What is the slew rate of MC3403N?

The MC3403N has a slew rate of 0.6 V/µs, which limits large-signal bandwidth to roughly 95 kHz at 20 V peak-to-peak output swing.

What is the pinout of MC3403N?

The MC3403N uses the standard quad op-amp pinout for a 14-pin DIP: outputs on pins 1, 7, 8, 14; inverting inputs on pins 2, 6, 9, 13; non-inverting inputs on pins 3, 5, 10, 12; V+ on pin 4; V- on pin 11. This matches the LM324 pinout, making the MC3403N a direct drop-in replacement in many circuits.

Can MC3403N replace LM324?

Yes, the MC3403N is pin-compatible with the LM324 and operates over a similar supply range (5–30 V vs. 3–32 V typical). The key differences are a slightly lower gain-bandwidth (1 MHz vs. 1.2 MHz typical for LM324) and a higher input bias current (200 nA vs. 20 nA typical). For non-critical DC or low-frequency AC applications, it is a direct functional substitute.
