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

How to use CA3130

Like all voltage Comparators the CA3130 also has an Inverting Pin and a Non-Inverting Pin. If the voltage at the Non-Inverting Terminal (pin 3) is high than the Inverting Terminal (pin 2) the output (pin 7) will also be high else the output will be low.

The CA3130 can work in a Single supply voltage or in a dual supply mode. For now let’s concentrate on the +5V supply voltage circuit since this is the most used design for digital circuits. In this type, the VCC+ (pin 8) is connected to +5V supply voltage and the VCC (pin 4) is grounded to hold it at 0V potential. A sample circuit is shown below

The special ability of this op-amp is to work wi

th high frequencies; it has a CMRR of 80dB and the rise time is as low as 0.09uS. This makes it ideal for voltage followers and other switching related applications
