Signal chain fit for high-speed analog front ends
The MAX4351ESA+ is a dual voltage-feedback amplifier from Analog Devices, built for signal chains that need to preserve pulse shape or wideband flatness through the analog front end. A 485 V/µs slew rate means the output can swing 5 V in about 10 ns — fast enough to pass a 10 MHz square wave without visible rounding, which matters for ADC driver stages or video distribution where the edge rate determines the settling time into the sampling window. The 210 MHz -3 dB bandwidth supports small-signal gains up to around 20 MHz before the closed-loop gain starts to roll off, so it fits applications like high-speed data acquisition, instrumentation front ends, or pulse amplifiers where the frequency content reaches into the tens of megahertz.
Supply rails, output swing, and thermal envelope
Supply span runs from 9 V minimum to 11 V maximum — a tight window that limits this part to single-rail or split-rail designs with well-regulated supplies, typically ±5 V. Each channel draws 6.9 mA supply current, totalling 13.8 mA for the dual package — modest enough that the 8-SOIC's thermal impedance handles continuous operation at 85 °C ambient without derating, as long as the output current per channel stays within the 80 mA limit.
Package, handling, and board integration
Surface-mount assembly, supplied in tube — the tube orientation is pin-1 at the indexing end, so it feeds into a pick-and-place tray without re-baking if kept in the original moisture-barrier bag.
Lifecycle and compliance posture
RoHS3 compliant — the part carries no restricted substances above the threshold, so it passes into EU and UKCA markets without an exemption declaration.
