IC CA3140AEZ
New Integrated circuitsAn operational amplifier that combines the advantages of high-voltage PMOS transistors and high-voltage bipolar transistors in the same package. A direct replacement for the TIP741 in most applications. Intended for applications such as long-duration timers, peak detectors, comparators, active filters, function generators, tone controls, portable instruments, etc. With a MOSFET input, it is characterized by a high input impedance. Package - DIP-8
