Maxim MAX4178/MAX4278 Datasheet
The MAX4178 and MAX4278 are +5 V, wide‑bandwidth, fast‑settling closed‑loop buffers featuring high slew rate, high precision, high output current, low noise, and low differential gain and phase errors. The MAX4178 is preset for unity voltage gain (0 dB) with a 330 MHz -3 dB bandwidth, while the MAX4278 provides a gain of +2 (6 dB) and a 310 MHz -3 dB bandwidth.
These devices are intended for high‑speed cable‑driving applications such as video routing, broadcast and HD‑TV systems, and precision high‑speed DAC/ADC buffers. They are available in DIP, SO, and space‑saving UMAX and SOT‑23 packages, and can drive capacitive loads up to 100 pF without oscillation when proper PCB layout techniques are used.
