Specifications of MAX4450EVKIT

Operating Supply Voltage
5 V or 9 V
The MAX4450 evaluation kit (EV kit) demonstrates the
capability of the high-speed MAX4450 operational
amplifier configured in a 3-pole, lowpass Sallen-Key fil-
ter which provides a Butterworth response with a band-
width of -3dB at 5.25MHz. This circuit can be used for
video anti-aliasing and reconstruction filtering. The cir-
cuit 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.
