MAX4181 - Maxim

MAX4181 Single/Dual/Quad / 270MHz / 1mA / SOT23 / Current-Feedback Amplifiers with Shutdown

The MAX4180 family of current-feedback amplifiers combines high-speed performance, low distortion, and excellent video specifications with ultra-low-power operation in miniature packages. They operate from ±2.25V to ±5.5V dual supplies, or from a single +5V supply. They require only 1mA of supply current per amplifier while delivering up to ±60mA of output c.
