Introduction to ca3130, ca3130 pinout, ca3130 power ratings, ca3130 applications
Hello 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.

  • The rise time of this device is 0.09uS and the CMRR is 80dB which makes it an ideal pick for the voltage followers and high-frequency applications.
