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 0.5V 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.
