Unity_gain_inverting_wideband_amplifier
This circuit shows the basic connections in a typical unity-gain inverting amplifier. The use of a compensation capacitor Cc is required for the AN104, unless the gain is fairly high. The AN103 only needs additional external compensation in special cases, such as when used as a noninverting unity-gain follower. Rd in the output circuit improves frequency stability. CF compensates for a pole in the closed-loop transfer function, caused by the input capacitance and feedback resistors. A ground plane is recommended, leads must be short, and Rf should not exceed 5.6 kΩ. Typical bandwidth is 35 MHz, with slew rates of 230 V/μs, into a 330-Ω load
