_______________General Desc ription
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 200
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 applica-
tions. A buffered bandgap reference voltage is avail-
able for the gain (contrast) and offset adjustments
along with a TTL BLANK input to turn off the output cur-
rent, independent of signal input.
The MAX445 is available in a 24-pin power-tab DIP
package. A suitable heatsink must be attached to
maintain the junction temperature within the recom-
mended operating range.
