General Description
The MAX445 is a high-performance, monolithic, variable gain transconductance amplifier with a high-voltage open-collector output capable of directly driving a video display (CRT cathode). A 2.5ns rise time is achieved using a peaking network with a 200Ω load resistor and an 8pF total load (CRT and parasitic capacitance).

FEATUREs
♦ 2.5ns Rise/Fall Time into an 8pF Load
♦ 200MHz Small-Signal Bandwidth
♦ 50Vp-p Output
♦ Ground Referenced Differential Inputs
♦ Linear Variable Gain for Contrast Control
♦ Offset Adjustment for Black Level
♦ 5.5V Bandgap Reference
♦ Drives 1280 x 1024 and 1530 x 1280 Displays

APPLICATIONs
    CRT Driver for High-Resolution Monochrome and Color Displays
    High-Voltage, Variable-Gain Transconductance Amplifier
