CA3028A, CA3028B,
CA3053
Differential/Cascode Ampli铿乪rs for Commercial
and Industrial Equipment from DC to 120MHz
Description
The CA3028A and CA3028B are differential/cascode
ampli铿乪rs designed for use in communications and industrial
equipment operating at frequencies from DC to 120MHz.
The CA3028B is like the CA3028A but is capable of pre-
mium performance particularly in critical DC and differential
ampli铿乪r applications requiring tight controls for input offset
voltage, input offset current, and input bias current.
The CA3053 is similar to the CA3028A and CA3028B but is
recommended for IF ampli铿乪r applications.
