Product Summary
The CA3280AE is a Dual, 9MHz, Operational Transconductance Amplifier. The CA3280AE consist of two variable operational amplifiers that are designed to substantially reduce the initial input offset voltage and the offset voltage variation with respect to changes in programming current. This design results in reduced AGC thump, an objectionable characteristic of many AGC systems. Interdigitation, or crosscoupling, of critical portions of the circuit reduces the amplifier dependence upon thermal and processing variables. The applications of the CA3280AE include Voltage Controlled Amplifiers, Voltage Controlled Oscillators, Multipliers, Demodulators, Sample and Hold, Instrumentation Amplifiers, Function Generators, Triangle Wave-to-Sine Wave Converters, Comparators and Audio Preamplifier.
