CA3420 0.5MHz/ Low Supply Voltage/ Low Input Current BiMOS Operational Amplifiers

CA3420, CA3420A TM Data Sheet April 2000 File Number 1320.6 0.5MHz, 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 protec.

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 2V to 20V either single or dual supply. These operational amplifiers are internally phase compensated to achieve stable operation in the unity gain follower configuration. Additionally, they have access terminals for a supplementary external capacitor if additional frequency roll-off is desired. Terminals are also provided for use in applications requiring input offset voltage nulling. The use of PMOS in the input stage resu.
