speed operational ampli鏗乪r capable of driving 50鈩?/div>
transmission lines and 鏗俛sh A/Ds. The uncompensated unity
gain crossing occurs at 230MHz without load. It can operate
at dual or single supplies of
鹵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.
