LM6181 is a high gain, frequency compensated, industry standard. 100 mA, 100 MHz Current Feedback Amplifier. LM6181 is a high-speed current feedback amplifier with typical slew rates of 2000 V/µs, settling time of 50 ns for 0.1%, and is fully specified and characterized for ±5 V, and ±15 V operation. The IC comes in an 8 – pin hermetically sealed dual in line IC packaging (DIP). LM6181 is highly preferred in applications where gain error detection and elimination is at first priority. The IC also offers a wide variety of features such as ESD protection, low thermal dissipation, and high noise immunity.
Current Feedback Amplifier
A Current feedback amplifier, as the name implies, is a general purpose electronic amplifier that utilizes a closed loop configuration in which the error signal is in the form of a Current difference. Ideally, a current feedback operational amplifier has low impedance inputs, resulting in zero input current, and also uses current feedback to maintain zero input voltage. Current feedback op-amps have excellent slew-rate capabilities. While it is possible to design a voltage-feedback amplifier with high slew rate, the current-feedback architecture is inherently faster.
