CA3420
0.5MHz, Low Supply Voltage, Low Input Current BiMOS Operational Amplifier
FN1320 Rev 9.00 Oct 4, 2005
The CA3420 is an integrated circuit operational amplifier that combines PMOS transistors and bipolar transistors on a single monolithic chip. The CA3420 BiMOS operational amplifier features 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 10°C increase in temperature. The CA3420 operates at total supply voltages from 2V to 20V either single or dual supply.
