Quad voltage-feedback amplifier with 150 MHz bandwidth and 600 V/µs slew rate
The MAX4020ESD+ is a quad voltage-feedback op-amp from Analog Devices, packing four independent amplifiers into a 14-SOIC package. Its 150 MHz -3dB bandwidth and 600 V/µs slew rate mean it can handle fast signal edges in video distribution, ADC front-end buffering, or high-speed data acquisition without slewing into nonlinearity.
Supply rails and output drive for signal-chain integration
Each of the four amplifiers draws 5.5 mA supply current, totalling 22 mA quiescent for the package — the thermal budget in the SOIC footprint is manageable at room temperature but worth checking at 85 °C ambient. Rail-to-rail output swing and 120 mA per-channel output current let it drive low-impedance loads like 50 Ω video lines or multiple ADC inputs directly. The 5.4 µA input bias current and 4 mV input offset voltage are typical for a high-speed voltage-feedback topology — adequate for AC-coupled paths but not a precision DC front-end.
