Overview of CA3280AE
The CA3280 and CA3280A types 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.Features• Low Initial Input Offset Voltage: 500µV (Max) (CA3280A)• Low Offset Voltage Change vs IABC: <500µV (Typ) for All Types• Low Offset Voltage Drift: 5µV/oC (Max) (CA3280A)• Excellent Matching of the Two Amplifiers for All Characteristics• Internal Current-Driven Linearizing Diodes Reduce the External Input Current to an Offset Component• Flexible Supply Voltage Range . . . . . . . . . . ±2V to ±15VApplications• Voltage Controlled Amplifiers• Voltage Controlled Oscillators• Multipliers• Demodulators• Sample and Hold• Instrumentation Amplifiers• Function Generators• Triangle Wave-to-Sine Wave Converters• Comparators• Audio Preamplifier
