CA3130 CMOS Operational Amplifier [Original]

CA3130 High-Performance CMOS Operational Amplifier (Op-Amp)

The CA3130 is a versatile CMOS Operational Amplifier, uniquely engineered to combine the best attributes of both CMOS and bipolar transistor technologies. Its input stage utilizes gate-protected P-Channel MOSFETs, delivering exceptionally high input impedance and remarkably low input current. This design ensures superior performance in sensitive applications requiring minimal signal loading. Furthermore, the CA3130 boasts an impressive common-mode input-voltage range, extending 0.5V below the negative supply rail, making it perfectly suited for single-supply designs. The innovative CMOS output stage allows for a true rail-to-rail signal swing, approaching within 10mV of either supply rail. With its exceptional speed performance, the CA3130 stands as an ideal choice for a wide array of precision and general-purpose electronic circuits.
