Add To BomCA3280AE General Description
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: 500V (Max) (CA3280A)
Low Offset Voltage Change vs IABC: <500V (Typ) for All Types
Low Offset Voltage Drift: 5V/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 15V
Application
Voltage Controlled Amplifiers
Voltage Controlled Oscillators
Multipliers
Demodulators
Sample and Hold
Instrumentation Amplifiers
Function Generators
Triangle Wave-to-Sine Wave Converters
Comparators
Audio Preamplifier
