Product Summary

The CA3280E is an operational Tranconductance amplifier. The CA3280E consists 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 CA3280E include Voltage Controlled Amplifiers, Voltage Controlled Oscillators, Multipliers, Demodulators, Sample and Hold, Instrumentation Amplifiers, Function Generators, Triangle Wave-to-Sine Wave Converters, Comparators, Audio Preamplifier.

Parametrics

CA3280E absolute maximum ratings: (1)Supply Voltage (Between V+ and V-): +36V; (2)Differential Input Voltage: 5V; (3)Input Voltage Range: V+ to VInput; (4)Current at ID = 0: 100μA; (5)Amplifier Bias Current (IABC): 10mA; (6)Output Short Circuit Duration: Indefinite; (7)Linearizing Diode Bias Current, ID: 5mA; (8)Peak Input Current with Linearizing Diode: ±ID.

Features

CA3280E features: (1)Low Initial Input Offset Voltage: 500μV (Max) (CA3280A); (2)Low Offset Voltage Change vs IABC:＜500μV (Typ) for All Types; (3)Low Offset Voltage Drift: 5μV/℃ (Max) (CA3280A); (4)Excellent matching of the Two Amplifiers for All Characteristics; (5) Internal Current-Driven Linearizing Diodes Reduce the External Input Current to an Offset Component; (6) Flexible Supply Voltage Range: ±2V to ±5V.
