CA3094B
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 100m A. This signal is sufficient to directly drive high current thyristors, relays, DC loads, or power transistors. The CA3094 has the generic characteristics of the CA3080 operational amplifier directly coupled to an integral Darlington power transistor capable of sinking or driving currents up to 100m A. The gain of the differential input stage is proportional to the amplifier bias current (IABC), permitting programmable variation of the integrated circuit sensitivity with either digital and/or analog programming signals. For example, at an IABC of 100µA, a 1m V change at the input will change the output from 0 to 100µA (typical). The CA3094 is intended for operation up to 24V and is especially useful for timing circuits, in automotive equipment, and in other applications where operation up to 24V is a...
