CA3094A中文资料INTERSIL数据手册PDF规格书

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.
