    February 11, 2015 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 В±1V supplies. It will also be suitable for 3.3V
    logic systems. Features The CA5420A 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 CA5420A
    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 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 results in common-mode input voltage capability ...
