Introduction to ca3130, ca3130 pinout, ca3130 power ratings, ca3130 applicationsHello Friends! Hope you’re well today. I welcome you on board. Thank you for clicking this read. In this post today, I’ll detail the Introduction to CA3130.The CA3130 is a BiMOS Operational Amplifier that comes with MOSFET. BiMOS is a term that defines the combination of both CMOS and bipolar op-amp technology into a single integrated circuit. CMOS op-amp is highly efficient that consumes less current while bipolar op-amp carries high bandwidth. Overall CA3130 is a device that combines the advantages of both bipolar and CMOS op-amp means it consumes less power and carries high bandwidth.I suggest you buckle as I’ll discuss the complete Introduction to CA3130 covering datasheet, pinout, features, and applications.Let’s get started.

Introduction to CA3130

  • The CA3130 is a BiMOS Operational Amplifier that incorporates MOSFET. It is widely used in Mobile jammers and oscillator circuits.
  • Incorporated in frequency generator, CA3130 carries input terminal current around 1mA and maximum output voltage around 13.3V.
  • The common-mode rejection ratio of this device is 80dB. This rejection ratio is the ability of the device to turn down common-mode signals. It is a ratio between differential mode gain and common-mode gain.

  • The CA3130 comes with high input impedance due to the presence of built-in MOSFETs. This also projects when the output voltage of the sensor is attached with the non-inverting and inverting pin of the op-amp, the resulting output voltage of the sensor doesn’t change its value.
  • If you are pondering for a device with less power consumption, fast sample rate, high input impedance, and high bandwidth, then this CA3130 op-amp might be the right fit for you.

How to Use CA3130

  • CA3130 carries both inverting and non-inverting pins.
  • The non-inverting pin is directly related to the inverting terminal and the output pin means when the voltage at the non-inverting pin is high then both inverting pin and output pin will be high.
  • The CA3130 operates as a single supply voltage with range 5V to 16V and as dual supply mode with range ±2.5V to ±8V.
  • Here in this example, we will take a single supply voltage with power supply 5V, as this is the most commonly used circuit.
  • In this circuit design, the pin 8 Vcc is attached with the 5V voltage supply while pin 4 is grounded where the potential difference is zero. A sample CA3130 circuit is given below.
