CA3450
File Number 1732.5
220MHz, Video Line Driver, High Speed
Operational Ampliï¬er
The CA3450 is a large signal video line driver and high
speed operational ampliï¬er capable of driving 50â¦
transmission lines and ï¬ash A/Ds. The uncompensated unity
gain crossing occurs at 230MHz without load. It can operate
at dual or single supplies of ±7.25V or 14.5V, respectively.
The CA3450 can be compensated with a single capacitor
network. It has output drive capability of 75mA SINK or
SOURCE. The CA3450 is capable of driving Flash A/Ds in
video or high speed instrumentation (accurate) applications
with bandwidth up to 10MHz. Offset voltage nulling terminals
are also available.
