The CA3130 is a high-input impedance operational amplifier (op-amp) with MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) inputs and a bipolar output.

Here's a Brief Description:

Functionality: The CA3130 is an operational amplifier, similar to the UA741, but it has MOSFET inputs, providing high input impedance and low input current.

Inputs and Outputs: Like most op-amps, the CA3130 typically has two inputs (inverting and non-inverting) and one output. It amplifies the voltage difference between its inputs.

Power Supply: The CA3130 usually operates with dual power supplies, commonly in the range of ±5 to ±15 volts. It can also work with a single power supply if a virtual ground is created.

High Input Impedance: One of the key features of the CA3130 is its high input impedance, making it suitable for applications where the input signal source has a high impedance.

MOSFET Inputs: The use of MOSFET inputs contributes to low input current, making it well-suited for applications where low input current is critical.

Unity Gain Bandwidth: The CA3130 has a specified unity gain bandwidth, indicating the frequency range within which the op-amp can operate with a gain of approximately one.

Low Offset Voltage: It typically has low offset voltage, which is beneficial for applications requiring precision.

Low Input Offset Current: The CA3130 generally has a low input offset current.

Temperature Range: The CA3130 is designed to operate within a specified temperature range.

Package Type: It is commonly available in an 8-pin dual in-line package (DIP).


The CA3130 is used in various applications, including transducer amplifiers, integrators, differentiators, voltage followers, and other analog signal processing circuits.
