CA3130EZ BiMOS Operational Amplifier: Schematic, Pinout, and Datasheet

CA3130 is a BiMOS operational amplifier IC with MOSFET Input and BiMOS devices have advantages of both bipolar and CMOS transistors. Bipolar transistors can perform fast switching and perform well under high bandwidths. On the other hand, CMOS op-amps consume less current. 

The CA3130 consists of PMOS transistors at the input and CMOS transistors at the output. These transistors provide the advantages of high impedance, high speed, less current consumption, and high bandwidth. The CA3130 circuits mainly operate at voltage supplies which range from 5V-16V. 

These circuits can be phase compensated through a single exterior capacitor & its terminals can be used for offset voltage adjustment where offset-null is required. Terminal supplies are made to allow the output stage strobing.

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 the sensor will not be disturbed. So if you are looking for an 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

CA3130 CMOS op-amp performs single & dual supply functions but the main difference between them is, the 4th pin is connected to GND in single-supply operation whereas the pin-8 strobes the o/p phase into quiescence.

This op-amp is used for compensation of phase to drive CMOS digital circuits within the applications of the comparator. Offset nulling is attained by connecting a potentiometer across pins 1 & 5.

The potentiometer’s slider arm is allied to pin 4 so that a fine value can be attained through sliding the arm. For obtaining effect compensation, a tiny capacitor is used in between pins 1 & 8. So for providing sufficient compensation, a 47pF capacitor is suitable.
