What the MAX412ESA+T is and where it fits
The Maxim Integrated MAX412ESA+T is a dual general-purpose op-amp in an 8-pin SOIC package, designed for signal conditioning, active filtering, and buffer stages in industrial and instrumentation circuits. It delivers a gain-bandwidth product of 28 MHz and a slew rate of 4.5 V/µs, which puts it in the mid-speed class — fast enough for audio-band and low-MHz sensor interfaces without the power penalty of a high-speed current-feedback amp. Supply span runs from 4.8 V to 10.5 V. Each of the two channels draws 2.5 mA quiescent current. Temperature range is -40°C to 85°C, suited for industrial control cabinets, outdoor telecom pedestals, and factory-floor sensor boards that see ambient warmth but not engine-bay heat.
28 MHz GBP and 4.5 V/µs slew rate — what they mean for the signal path
The 28 MHz gain-bandwidth product sets the closed-loop bandwidth at a given gain. The 4.5 V/µs slew rate limits large-signal swing at higher frequencies. Input offset voltage is 120 µV typical, and input bias current is 80 nA — both unremarkable for a general-purpose bipolar op-amp but fine for DC-coupled stages where the error budget allows a few millivolts of offset. If your design needs microvolt-level precision, this is not the part; look at a chopper-stabilized amp instead.
Package and supply details for the BOM line
The MAX412ESA+T comes in an 8-pin SOIC package (body 3.90 mm wide), surface-mount only. If your line runs tube or tray, check whether the distributor can split the reel or if you need the tube variant (MAX412ESA+).
Lifecycle and sourcing — no LTB risk here
The MAX412ESA+T carries an Active lifecycle status with ROHS3 compliance. For a BOM freeze or a new design, there is no imminent obsolescence risk to track.
