描述 Description

30MHz, High Output Current Operational Transconductance Amplifier (OTA)The CA3094 is a differential input power control switch/amplifier with auxiliary circuit features for ease of
programmability. For example, an error or unbalance signal can be amplified by the CA3094 to provide an on-off signal or proportional control output signal up to 100mA. This signal is sufficient to directly drive high current thyristors, relays, DC loads, or power transistors.
