CA3140EZ 10pA Single 4.5MHz 5mV DIP-8 Operational Amplifier

From the shop's description

CA3140EZ Description The single-chip, monolithic integrated circuits CA3140A and CA3140 provide the advantages of both high-voltage PMOS and high-voltage bipolar transistors. The input circuit of the CA3140 and CA3140A BiMOS operational amplifiers uses gate-shielded MOSFET transistors to provide extremely high input impedance, extremely low input current, and high-speed performance. The benefits of high-voltage PMOS and bipolar transistors are combined onto a single monolithic chip in operational amplifiers like the CA3140A and CA3140. The gate-protected MOSFET transistors used in the input circuit of the CA3140 and CA3140A BiMOS operational amplifiers provide extremely low input current, exceptionally high input impedance, and high-speed performance. The input stage’s common mode input voltage capability can be as low as 0.5V below the negative supply terminal thanks to using PMOS field effect transistors, a crucial feature for single supply applications. The output stage, which uses bipolar transistors and has built-in protection against short circuit damage from the load terminal to the supply rail or the ground, is likewise protected against short circuit damage. It is designed for the CA3140 and CA3140A to operate at supply voltages up to 36V (or about 18V).
