Product details

1 MHz quad op-amp — what the ratings mean on the bench

The MC3303DT is a quad general-purpose op-amp from STMicroelectronics, packing four independent amplifiers in a single 14-SOIC package. For audio-band sensor conditioning or 4-20 mA loop buffers, this is plenty; for video or fast ADC drivers, you will want a faster part. The 2.8 mA total quiescent current for all four channels keeps the thermal budget modest in a tight enclosure.

Temperature grade and package — field-replaceable fit

No special orientation tricks — pin 1 is marked on the package top. For DC-coupled signals from a thermocouple or a strain-gauge bridge, the offset adds a DC error you can null with a trim pot or compensate in firmware.

Active lifecycle and compliance — no sourcing surprises

No end-of-life notice, no last-time-buy clock ticking.

Frequently asked questions

What is MC3303DT's slew rate and what does it mean for my signal?

The MC3303DT has a slew rate of 0.5 V/µs. At unity gain, the full-power bandwidth is about 80 kHz before the output starts slewing. For audio signals up to 20 kHz or slow sensor outputs, it is clean; for fast square waves or video, you will need a faster op-amp.

Will MC3303DT drop into a board designed for MC1458IDT?

Not without a layout change. The MC1458IDT is a dual op-amp in an 8-pin SOIC; the MC3303DT is a quad in a 14-pin SOIC. The pinouts are different, and the extra two amplifiers on the MC3303DT need PCB traces. If you only need two amplifiers, the LM2902DT (quad, 14-SOIC) is a closer parametric match with 800 kHz GBW and 0.4 V/µs slew rate.
