Operating Considerations
"Sink" Output (Terminal "Drive" Output (Terminal CA3094 inherently current power) limited. Therefore, load connected between Terminal Terminal Ground), important connect current limiting resistor between Terminal Terminal (V+) protect transistor under shorted load conditions. Similarly, load connected between Terminal Terminal (V+), current limiting resistor should connected between Terminal Terminal ground. circuit applications where emitter output transistor connected most negative potential system, recommended that current limiting resistor inserted between Terminal supply.

Design Considerations selection optimum amplifier bias current (IABC) depends Desired Sensitivity higher IABC, higher sensitivity, i.e., greater drive current capability output specific voltage change input. Required Input Resistance lower IABC, higher input resistance. desired sensitivity required input resistance known experimentally determined, anticipated equipment design sufficiently flexible tolerate wide range these parameters, recommended that equipment designer begin calculations with IABC 100µA, since CA3094 characterized this value amplifier bias current.
