28 MHz GBW — what it buys the signal chain
The MAX412BEPA is a dual general-purpose op-amp from Maxim, built for applications that need more bandwidth than a 1 MHz jellybean part but don't require a dedicated high-speed amplifier. Its 28 MHz gain-bandwidth product supports signal conditioning up to several megahertz — think fast ADC drivers, active filters in the low-MHz range, or video buffering at standard-definition rates. The 4.5 V/µs slew rate means the large-signal response keeps up with pulses around 1 V/µs per channel; if you need to swing the full rail at 5 V, the full-power bandwidth settles around 700 kHz, so check the output swing against your signal frequency.
Supply range and input accuracy for the BOM
The part runs from a single or split supply spanning 4.8 V to 10.5 V, which covers standard 5 V and ±5 V rails. Input bias current is 80 nA, so source impedance matters: a 10 kΩ source adds 0.8 mV of offset error, which is acceptable for 12-bit systems but worth derating for 16-bit. Each channel delivers 35 mA output current, enough to drive a 100 Ω load to within a volt of the rails.
Package and temperature grade — fit for industrial builds
Housed in an 8-pin PDIP (0.300" wide, 7.62 mm pitch), the MAX412BEPA is a through-hole part.
