Quad op-amp in a 14-SOIC — 1 MHz GBW, 0.6 V/µs slew rate
The STMicroelectronics MC3403D is a quad general-purpose operational amplifier in a 14-SOIC surface-mount package. The supply span runs from 5 V single supply up to 30 V, making it compatible with both 5 V logic rails and ±15 V industrial supplies.
The 5 V minimum supply means this part runs cleanly off a single 5 V rail without a negative supply. At the other end, the 30 V maximum covers ±15 V split supplies common in industrial signal conditioning. The 2.8 mA total quiescent current across four amplifiers is moderate — budget it against the system power budget, especially in multi-channel designs where every milliamp matters.
It is ROHS3 compliant.
