The MAX4223-MAX4228 current-feedback amplifiers combine ultra-high-speed performance, low distortion, and excellent video specifications with low-power operation. They are ideal for professional video applications, with excellent differential gain and phase errors. The low-power shutdown mode makes them suitable for portable and battery-powered applications.
The MAX4223‑MAX4228 family are ultra‑high‑speed, low‑power current‑feedback amplifiers featuring up to 1 GHz ‑3 dB bandwidth, 0.1 dB gain flatness to 300 MHz, and a shutdown mode that reduces supply current to 350 µA. They operate from dual ±2.85 V to ±5.5 V supplies and are available in compact 6‑pin SOT23 and 10‑pin µMAX packages.
The datasheet provides detailed electrical characteristics, pin descriptions, typical operating curves, layout recommendations, and AC performance data, enabling designers to implement the amplifiers in video, data‑communication, and ADC input buffer applications.
