The CA158, CA158A, CA258, CA358, CA358A and CA2904 types consist of two independent, high gain, internally frequency compensated operational amplifiers which are designed specifically to operate from a single power supply over a wide range of voltages. They may also be operated from split power supplies. The supply current is basically independent of the supply voltage over the recommended voltage range.

These devices are particularly useful in interface circuits with digital systems and can be operated from the single common 5VDC power supply. They are also intended for transducer amplifiers, DC gain blocks and many other conventional op amp circuits which can benefit from the single power supply capability.

The CA158, CA158A, CA258, CA358, CA358A, and CA2904 types are an equivalent to or a replacement for the industry types 158, 158A, 258, 258A, 358, 358A, and CA2904.
