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 premium performance particularly in critical DC and differential amplifier applications requiring tight controls for input offset voltage, input offset current, and input bias current.

FEATUREs
• Controlled for Input Offset Voltage, Input Offset
Current and Input Bias Current (CA3028 Series Only)
• Balanced Differential Amplifier Configuration with
Controlled Constant Current Source
• Single-Ended and Dual-Ended Operation

APPLICATIONs
• RF and IF Amplifiers (Differential or Cascode)
• DC, Audio and Sense Amplifiers
• Converter in the Commercial FM Band
• Oscillator
• Mixer
• Limiter
