The ADA4625-2ARDZ-R7: The 0.154-inch body width (3.90 mm) is standard SOIC-8 footprint compatible, but the exposed paddle requires a larger central pad and via array than a standard SOIC-8 land pattern.
Slew rate and signal fidelity
A 48 V/µs slew rate paired with 18 MHz gain-bandwidth product means this JFET input stage can swing large output voltages at high frequencies without slewing — useful for driving ADC inputs or fast waveform generation where settling time matters. The -3 dB bandwidth of 16 MHz confirms the usable small-signal bandwidth, though the actual large-signal bandwidth is slew-rate limited: at full 36 V swing the output can transition in under 0.75 µs.
