Description
The CA3028A and CA3028B are differential/cascode
ampli?ers 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?er applications requiring tight controls for input offset
voltage, input offset current, and input bias current.
