DATASHEET CA3130, CA3130A 15MHz, BiMOS Operational Amplifier with MOSFET Input/CMOS Output FN817 Rev.6.00 Aug 1, 2005 CA3130A and CA3130 are op amps that 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.
