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.
