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 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 bandwidth of 240MHz and a 0.1dB bandwidth of 70MHz. The MAX4181/MAX4184/MAX4185/MAX4187 are compensated for applications with a +1 (0dB) or greater gain, and provide a -3dB bandwidth of 270MHz and a 0.1dB bandwidth of 60MHz. The MAX4180–MAX4187 feature 0.08%/0.03° differential 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 shutdown 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. The single MAX4180/MAX4181 are offered in space-saving 6-pin SOT23 packages.
The MAX4180 series from Maxim Integrated are current‑feedback amplifiers designed for high‑speed video and multimedia applications. They operate from ±2.25 V to ±5.5 V dual supplies or from a single +5 V supply, drawing only 1 mA per amplifier in normal mode and offering up to ±60 mA output current.
Key features include ultra‑low supply current, a shutdown mode that reduces consumption to 135 µA, bandwidths up to 245 MHz, a 450 V/µs slew rate, and a 20 ns settling time to 0.1 %.
