Applications
MC3403NE4 is used in industrial sensor conditioning boards where 4 independent amplifier channels are needed for analog signal scaling, filtering, and buffering in a single IC. Its wide supply voltage range of 3 V to 36 V makes it suitable for automotive and industrial control systems operating from unregulated supplies. It also serves in audio preamplifier stages, comparator circuits, and active filter designs that require low-cost quad op-amp solutions.

Frequently Asked Questions
How many independent amplifier channels does MC3403NE4 provide, and what is its unity-gain bandwidth?
MC3403NE4 contains 4 independent op-amp channels in a single 14-pin DIP package. The unity-gain bandwidth is 1 MHz, which is suitable for audio signal amplification and low-frequency sensor conditioning applications up to the mid-frequency range. Each channel operates independently, allowing designers to implement multiple amplifier stages without additional ICs.
What supply voltage configurations are compatible with MC3403NE4 in industrial control designs?
MC3403NE4 operates from a single supply of 3 V to 36 V or a dual supply of ±1.5 V to ±18 V, giving designers flexibility across different power architectures. This wide range accommodates 5 V logic systems, 12 V automotive rails, and 24 V industrial bus supplies without additional regulation. The input common-mode voltage range includes ground potential, enabling direct sensing of ground-referenced signals without level-shifting circuitry.
In what signal conditioning roles does the quad channel count of MC3403NE4 reduce BOM cost compared to single op-amps?
Using MC3403NE4 replaces up to 4 individual single op-amp packages, reducing component count and PCB area by approximately 75% in multi-channel designs. Each of the 4 channels delivers a typical input offset voltage of 5 mV and slew rate of 0.6 V/µs, sufficient for industrial sensor amplification chains. Common use cases include 4-channel thermocouple signal conditioners, bridge amplifier arrays, and multi-axis accelerometer interfaces.
How does MC3403NE4 compare to LM324 when selecting a quad op-amp for a 5 V single-supply audio application?
MC3403NE4 and LM324 share the same quad channel topology and similar 1 MHz unity-gain bandwidth at 5 V supply, making them functionally interchangeable in most audio preamplifier designs. MC3403NE4 in the 14-pin DIP NE4 package is a commercial-grade part rated from 0°C to 70°C, while LM324 covers a similar range. Both draw a supply current of approximately 0.7 mA per channel at 5 V, keeping total quiescent power below 14 mW for the quad device.
