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.
