Description

The CA3028A and CA3028B are differential/cascode amplifiers 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 amplifier 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 amplifier applications. Pinouts Schematic Diagram (Terminal Numbers Apply to All Packages)
