5MHz, Low Supply Voltage, Low Input Current BiMOS Operational Amplifiers
The CA3420A and CA3420 are integrated circuit operational amplifiers that combine PMOS
transistors and bipolar
transistors on a single monolithic chip.
The CA3420A and CA3420 BiMOS operational amplifiers feature gate protected 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 CA3420 series operates at total supply voltages from 2...
