4200V/µs slew rate defines the signal ceiling
The MAX4203ESA+ is a dual-channel buffer amplifier from Analog Devices with a 4200V/µs slew rate and 530 MHz -3dB bandwidth. This combination means the output can track a full-scale step of several volts in under a nanosecond — the limiting factor in a high-speed ADC driver or video line driver is the input signal's rise time, not the buffer's. The 2.2mA supply current per channel and 90mA output drive keep the thermal budget manageable for a closed-loop system running both channels continuously.
Dual-channel in a standard 8-SOIC footprint
Two independent buffer circuits in the 8-SOIC package — the pinout is the same as a dual op-amp, so the PCB layout reuses an existing footprint. Surface-mount assembly with tube handling; the 8-SOIC body is 3.90 mm wide, which fits most pick-and-place feeders without changeover. The 1 mV input offset voltage and 800 nA input bias current are typical for a high-speed buffer; the offset matters if the DC level at the output must stay within a few millivolts of the input.
Active production with industrial temperature coverage
The 8V to 11V supply span matches standard ±5V rails or a single 10V rail; the buffer's common-mode range tracks the supply, so a single-supply design loses headroom on the negative swing.
