Quad voltage-feedback amp with 500V/µs slew rate
The Maxim Integrated MAX4395EUD+ is a quad-channel voltage-feedback operational amplifier in a 14-TSSOP package. Its 500V/µs slew rate and 85 MHz -3dB bandwidth make it a fit for video distribution, high-speed ADC drivers, and pulse-processing front ends where signal fidelity through fast edges matters. Rail-to-rail output swing lets it drive into the full supply range without headroom loss — useful in single-supply 5V or 3.3V systems where every millivolt of dynamic range counts.
The part runs from a single 4.5V to 11V supply or split rails of ±2.25V to ±5.5V. That covers 5V logic rails, 9V battery packs, and standard ±5V analog supplies without a secondary regulator. Each of the four channels can source or sink 95 mA, enough to drive 50Ω back-terminated video lines or a bank of sampling ADC inputs directly. Total quiescent draw is 6 mA per amplifier, so a quad-channel design pulls 24 mA idle — budget that into the power rail sizing for portable or multi-channel boards.
Package and assembly
Housed in a 14-TSSOP (4.40 mm width) with a surface-mount footprint. The Tube shipping medium is standard for prototype and low-volume builds; reel options exist for production. The 0.65 mm pitch demands a decent solder-paste print; no tombstoning risk with the four-channel layout if pad geometry follows the IPC-7351 nominal.
ROHS3 compliant, so it clears EU and California regulatory gates without an exemption certificate.
