    Oct 4, 2005 0.5MHz, Low Supply Voltage, Low Input Current BiMOS Operational Amplifier
    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 10В°C
    increase in temperature. The CA3420 operates at total
    supply voltages from 2V to 20V either single or dual supply.
    This operational amplifier is internally phase compensated to
    achieve stable operation in the unity gain follower
    configuration. Additionally, it has access terminals for a
    supplementary external capacitor if additional frequency rolloff is desired. Terminals are also provided for use in
    applications requiring input offset voltage nulling. The use of
    PMOS in the input stage results in common mode input
    voltage capability down to 0.45V below the negative supply
    terminal, an important attribute for single supply application.
    The output stage uses a feedback OTA type amplifier that ...
