The CA3130AMZ is a single BiMOS Operational Amplifier with MOSFET input/CMOS output. The CA3130A is combine the advantage of both CMOS and bipolar transistors. Gate-protected P-channel MOSFET (PMOS) transistors are used in the input circuit to provide very-high-input impedance, very-low-input current and exceptional speed performance. The use of PMOS transistors in the input stage results in common-mode input-voltage capability down to 0.5V below the negative-supply terminal, an important attribute in single-supply applications. A CMOS transistor-pair, capable of swinging the output voltage to within 10mV of either supply-voltage terminal (at very high values of load impedance), is employed as the output circuit. It can be phase compensated with a single external capacitor and has terminals for adjustment of offset voltage for applications requiring offset-null capability. Terminal provisions are also made to permit strobing of the output stage.
