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 the Fairchild CA3280 integrated circuit. This is an opera- tional transconductance amplifier (OTA) operated as a com- parator. An OTA is a current output circuit The CA3080 and CA3080A types are Gatable-Gain Blocks which utilize the unique operational-transconductance- amplifier (OTA) concept described in Texas Instruments and its subsidiaries (TI) reserve the right to make changes to their products or to discontinue any product or service without notice, and advise amplitude, and distortion levels.
