DescriptionThe MAX4187 of current-feedback amplifiers combines high-speed performance, low distortion, and excellent video specifications with ultra-low-power operation in miniature packages. The MAX4187 operates from ±2.25V to ±5.5V dual supplies, or from a single +5V supply. They require only 1mA of supply current per amp- lifier while delivering up to ±60mA of output current drive. The MAX4180/MAX4182/MAX4183/MAX4186 are compensated for applications with a closed-loop gain of +2 (6dB) or greater, and provide a -3dB band- width of 240MHz and a 0.1dB bandwidth of 70MHz.
The MAX4181/MAX4184/MAX4185/MAX4187 are com- pensated for applications with a +1 (0dB) or greater gain, and provide a -3dB bandwidth of 270MHz and a 0.1dB bandwidth of 60MHz. The MAX4187 feature 0.08%/0.03°differen- tial gain and phase errors, a 20ns settling time to 0.1%, and a 450V/µs slew rate, making them ideal for high- performance video applications. The MAX4180/MAX4181/ MAX4183/MAX4185 have a low-power shut- down mode that reduces power-supply current to 135µA and places the outputs in a high-impedance state. This feature makes them ideal for multiplexing applications.
