... The linear variation of the parameters with respect to bias and the ability to maintain a constant DC level between input and output of each amplifier also makes the CA3060 suitable for a variety of nonlinear appli- cations such as mixers, multipliers, and modulators. In addition, the CA3060 incorporates a unique Zener diode regulator system that permits current regulation below sup- ply voltages normally associated with such systems ...

... Capacitance Effects The CA3060 is designed to operate at such low power levels that high impedance circuits must be employed. In designing such circuits, particularly feedback amplifiers, stray circuit capacitance must always be considered because of its adverse effect on frequency response and stability ...

... CA3060 Circuit Description Figure 23 shows the block diagram of a tri-level comparator using the CA3060. Two of the three amplifiers are used to compare the input signal with the upper limit and lower limit reference voltages. The third amplifier is used to compare the input signal with a selected value of intermediate limit reference voltage ...
