CA3130

15MHz, BiMOS Operational Amplifier with MOSFET Input/CMOS Output. CA3130 is op amp that combines 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 CA3130 can operate at supply voltages ranging from 5V to 16V, (±2.5V to ±8V). CA3130 is an operational amplifier which combines the advantage of both CMOS and a bipolar transistor on a single chip. Operating voltage range varies from 5V to 16V. CA3130 has an advantage that they can be phased compensated with a single external capacitor and have terminals for adjustment of offset voltage. In this, you can adjust the reference voltage at inverting and non-inverting pin so that when the voltage at inverting pin is more than non-inverting pin. It will make the out pin high and vice versa.
