High-speed voltage feedback amp for pulse and ADC drive
The LMH6624MAX/NOPB: Its 1.5 GHz gain bandwidth product and 400V/µs slew rate make it a natural fit for driving high-speed ADCs, video distribution, pulse amplification, and timing circuits where the output must slew through several volts in a few nanoseconds. The -3dB bandwidth of 95 MHz and output current capability of 100 mA per channel support driving capacitive loads or multiple terminated lines. Supply span runs from 5 V to 12 V, so it works on a single 5 V or ±5 V rail, but the 5 V minimum means it won't run from a 3.3 V supply — keep that in mind when selecting rails.
The 5 V to 12 V supply span gives headroom for a regulated 5 V rail or a 12 V industrial bus, but the 5 V minimum excludes low-voltage portable designs. Input bias current is 13 µA (bipolar input stage), which is higher than a CMOS-input amp but typical for a high-speed voltage feedback topology. Input offset voltage is 100 µV, tight enough for precision gain stages without external trimming.
Package and mounting
Standard SOIC-8 land pattern applies; no thermal pad to worry about, but the 100 mA output current and 12 mA quiescent mean junction temperature stays manageable in most layouts without forced airflow.
If you're dual-sourcing for supply resilience, the closest parametric peer is the THS4215DRBT (also voltage feedback, 970 V/µs slew, 350 MHz bandwidth, but -40°C to 85°C only), though the LMH6624's wider temperature range and higher GBW may be the deciding factor for industrial designs.
