The MAX4223EUT+T is a 1GHz, low power, current feedback amplifier with shutdown in 6 pin SOT-23 package. This current feedback amplifier combines ultra high-speed performance, low distortion and excellent video specifications with low power operation. It has a shutdown feature that reduces power supply current to 350µA and places the outputs into a high impedance state. It is optimized for a closed-loop gain of +1(0dB) or more and has a -3dB bandwidth of 1GHz. This device suitable for driving high-speed analogue to digital inputs or for data communication applications. The low power shutdown mode on the device makes it suitable for portable and battery-powered applications. Their high output impedance in shutdown mode is excellent for multiplexing applications. Typical applications include ADC input buffers, video cameras, video line drivers, video switches, video editors, XDSL drivers, RF receivers and differential line drivers.
