CA5420A, 0.5MHz/ Low Supply Voltage/ Low Input Current BiMOS Operational Amplifiers

CA5420A Data Sheet September 1998 File Number 1925.4 0.5MHz, Low Supply Voltage, Low Input Current BiMOS Operational Ampliﬁers The CA5420A is an integrated circuit operational ampliﬁer that combines PMOS transistors and bipolar transistors on a single monolithic chip.

It is designed and guaranteed to operate in microprocessor logic systems that use V+ = 5V, V- = GND, since it can operate down to ±1V supplies.

It will also be suitable for 3.3V logic systems.

CA5420A Features

* gateprotected PMOS transistors in the input circuit to provide very high input impedance, very low input currents (less than 1pA). The internal bootstrapping network features a unique guardbanding technique for reducing the doubling of leakage current for every 10oC increase in temperature. The CA54
