19-0302; Rev 0; 9/94 Low-Cost, High-Resolution, 200MHz Video CRT Driver _______________General Description The MAX445 is a high-performance, monolithic, variablegain 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). Differential inputs and a linear adjustable gain stage with an output offset adjustment make the versatile MAX445 well suited for many video display applications. A buffered bandgap reference voltage is available for the gain (contrast) and offset adjustments along with a TTL BLANK input to turn off the output current, independent of signal input.
