The CA3130 is a BiMOS Operational Amplifier with MOSFET. The term BiMOS implies that it combines the advantage of both Bipolar and CMOS op-amp technology. Bipolar op-amps perform well under high bandwidths (fast switching) and CMOS op-amps perform well by consuming less current. So the CA3130 being a BiMOS op-amp has the advantage of high bandwidth operation and less current consumption.
The op-amp is built using MOSFETS and hence it has high input impedance. Meaning, when a sensor’s output voltage is connected to the inverting or non-inverting pin of the op-amp, the op-amp will not act as a load to the sensor and thus the output voltage from sensor will not be disturbed. So if you are looking for a Op-amp with high bandwidth, fast sample rate, less power consumption and high input impedance then this op-amp might be the right choice for you
