EL5191, EL5191A 1GHz Current Feedback Amplifier with Enable
The EL5191 and EL5191A are 1 GHz current‑feedback amplifiers designed for high‑speed video, monitor, RF and IF applications. They operate from a single or dual supply of 5 V to 10 V and draw only 9 mA (100 µA in disabled mode for the EL5191A). Both devices function over an industrial temperature range of –40 °C to +85 °C.
The document includes detailed electrical specifications, absolute maximum ratings, typical performance curves, and example application circuits. Package options include 5‑pin SOT‑23 for the EL5191 and 6‑pin SOT‑23 or 8‑pin SO for the EL5191A, with RoHS‑compliant, lead‑free options available.
