CA3028A, CA3028B, CA3053
Differential/Cascode Amplifiers for Commercial and Industrial Equipment from DC to 120MHz
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. The CA3053 is similar to the CA3028A and CA3028B but is recommended for IF amplifier applications.
November 1996
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 * 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

Glossary of Terms
AGC Bias Current The current drawn by the device from the AGC voltage source, at maximum AGC voltage. AGC Range The total change in voltage gain (from maximum gain to complete cutoff) which may be achieved by application of the specified range of dc voltage to the AGC input terminal of the device. Common Mode Rejection Ratio The ratio of the full differential voltage gain to the common mode voltage gain. Power Dissipation The total power drain of the device with no signal applied and no external load current. Input Bias Current The average value (one half the sum) of the currents at the two input terminals when the quiescent operating voltages at the two output terminals are equal. Input Offset Current The difference in the currents at the two input terminals when the quiescent operating voltages at the two output terminals are equal. Input Offset Voltage The difference in the DC voltages which must be applied to the input terminals to obtain equal quiescent operating voltages (zero output offset voltage) at the output terminals. Noise Figure The ratio of the total noise power of the device and a resistive signal source to the noise power of the signal source alone, the signal source representing a generator of zero impedance in series with the source resistance. Power Gain The ratio of the signal power developed at the output of the device to the signal power applied to the input, expressed in dB. Quiescent Operating Current The average (DC) value of the current in either output terminal. Voltage Gain The ratio of the change in output voltage at either output terminal with respect to ground, to a change in input voltage at either input terminal with respect to ground, with the other input terminal at AC ground.
