Product Summary

The MAX457CPA is a dual CMOS video amplifier. It contains two unity-gain stable video amplifiers that are capable of driving 75Ω loads with a -3dB bandwidth of 70MHz. The MAX457CPA operates from ±5V supplies and together consume about 350mW of power. Closed loop gain is set by two external resistors. The input of the MAX457CPA follows that of conventional 8-pin, dual op amp. The applications of the MAX457CPA include 75Ω cable drivers, output amplifiers for Video Cross point switches, high speed, low gain applications, driving flash converters, and video distribution amplifiers.
