CA3280, Dual 9MHz Operational Transconductance Amplifier (OTA)

® CA3280, CA3280A Data Sheet May 2002 FN1174.6 Dual, 9MHz, Operational Transconductance Amplifier (OTA) 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.
