The is a single BiMOS Operational Amplifier with MOSFET input/bipolar output. The CA3140A is combines the advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolithic chip. The CA3140A BiMOS operational amplifier feature gate protected MOSFET PMOS transistors in the input circuit to provide very high input impedance, very low input current and high speed performance. This operational amplifier is internally phase compensated to achieve stable operation in unity gain follower operation and additionally, has access terminal 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 field effect transistors in the input stage results in common mode input voltage capability down to 0.5V below the negative supply terminal.
