Single-supply voltage feedback amp in SOT-23-5
The MAX4390EUK+T: It delivers a 500V/µs slew rate and 85 MHz -3dB bandwidth, making it suited for high-speed signal conditioning in video, communications, and test equipment where a compact footprint is required.
Rail-to-rail output and supply flexibility
The rail-to-rail output stage swings within millivolts of both supply rails, preserving dynamic range in single-supply systems. The amplifier operates from a single 4.5V to 11V supply or a dual ±2.25V to ±5.5V supply, covering common 5V and ±5V rails without an extra regulator. Quiescent supply current is 6 mA, and each channel can deliver 95 mA of output current — enough to drive 50-ohm back-terminated video lines or multiple ADC inputs through a mux.
