High-speed voltage feedback amp in 8-SOIC
The MAX4104ESA+ is a single-channel voltage feedback amplifier from Analog Devices, built for applications that need wide bandwidth and fast settling without the supply penalty of a current-feedback topology. The 625 MHz -3dB bandwidth and 400V/µs slew rate make it a fit for video distribution, ADC drivers, and high-speed instrumentation front-ends where the signal path must preserve pulse edges and harmonic content up to several hundred megahertz. The tube packaging suits prototype and low-volume production runs; for reel quantities the same die is available in the tape-and-reel variant.
The 625 MHz -3dB bandwidth is the small-signal limit; the actual large-signal bandwidth is governed by the 400V/µs slew rate. For a 2 Vpp output swing, the full-power bandwidth calculates to roughly 32 MHz — above that the output slew-rate limits the undistorted swing. This matters when driving an ADC input or a cable: if the required output step exceeds the slew-limited risetime, the signal distorts before the bandwidth limit is reached. Supply current is 20 mA typical — modest for this speed class. The 7 V to 11 V supply span means it runs from a single 8 V or 9 V rail, or split ±5 V supplies, without needing a separate low-voltage rail. No AEC-Q100 grade is listed, so it is not qualified for under-hood automotive deployment.
Active production and compliance documentation
RoHS3 compliant (2011/65/EU + 2015/863), with no exemptions listed. The part is lead-free and compatible with standard reflow profiles. No REACH, UL, or IEC certification is cited in the available documentation; for compliance certificate requests, the lot-specific documentation is confirmed at the time of order.
