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

• Limiter
• Related Literature
- Application Note AN5337 “Application of the
CA3028 Integrated Circuit Amplifier in the HF and
VHF Ranges.” This note covers characteristics of
different operating modes, noise performance,
mixer, limiter, and amplifier design considerations
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.
