The MAX4450 evaluation kit (EV kit) demonstrates the capability of the high-speed MAX4450 operational amplifier configured in a 3-pole, lowpass Sallen-Key filter which provides a Butterworth response with a bandwidth of -3dB at 5.25MHz. This circuit can be used for video anti-aliasing and reconstruction filtering. The circuit is designed to drive a 75Ω termination, common in video applications, with an overall gain of 1. The MAX4450 EV kit board operates from a ±2.25V to ±5.5V dual-voltage supply or a +4.5V to +11V single-voltage supply. The MAX4450 EV kit is a fully assembled and tested surface-mount board.
