General Description

The MAX4005 is a ±5V, single-ended unity-gain buffer with a high-impedance JFET input, intended to drive a 75Ω load. A 75Ω thin-film output resistor is included onboard to minimize reflections when driving a 75Ω load through a transmission line of arbitrary length. Gain in this configuration is 0.5.
