Dual voltage-feedback op-amp with 200 V/µs slew rate
Slew rate and bandwidth — what they mean for signal integrity
The 200 V/µs slew rate is the headline here: it supports full-power bandwidth into the hundreds of kilohertz for large-signal pulses, useful in waveform generation, video buffering, or fast ADC drivers where settling time matters. The 3 MHz gain-bandwidth product sets the small-signal bandwidth — at a gain of 10, expect about 300 kHz closed-loop bandwidth. That combination (fast slew, moderate GBP) is typical of current-feedback-like topologies in a voltage-feedback part, giving the designer a clean large-signal response without the stability quirks of a true current-feedback amp.
It is ROHS3 compliant. The ADA4805-2ARMZ is a dual voltage-feedback amp with 120 MHz GBP and 250 V/µs slew rate, but it runs from a 2.7 V minimum supply and draws 600 µA per channel — a different power/speed tier. No pin-compatible drop-in exists; the LT1352IS8#PBF is the part to qualify.
