Introduction to jrc4558, jrc4558 pinout, jrc4558 power ratings, jrc4558 applications
Hi Guys! Happy to see you around. I welcome you on board. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to JRC4558. The JRC4558 is a single silicon-chip monolithic dual operational amplifier. This amplifier is a high-performance device and is internally compensated. It is widely used in sample and hold amplifiers and pedal circuit designs. The JRC4558 is available with remarkable input impedance around 5 MO, high voltage gain around 100 dB, and a good slew rate around 1.7V/µs. I suggest you buckle up as I will walk you through the complete introduction to JRC4558 covering datasheet, pinout, features, alternatives, and applications. Let’s jump right in.

Introduction to JRC4558

  • The JRC4558 is a single silicon-chip monolithic dual operational amplifier that comes with high voltage gain and good input impedance.
  • It is applied in portable instrumentation and Intrusion Alarm System.
  • There are total eight pins incorporated on the device where pin number 8 is the voltage supply pin and pin no 4 is the ground pin. And you’ll get two outputs at the same time.
  • There are two inputs i.e. input A and input B and both inputs contain one inverting input (-) with Voltage V- and non-inverting input (+) with voltage V+.
  • The ideal op-amps are different from the real op-amp used in this chip. The ideal op-amp comes with infinite gain while the voltage gain of this device is finite and is around 100dB.
  • The slew rate of this device is around 1.7V/µs which is achieved when the output voltage of the amplifier is reached its maximum rate of change.

  • This chip is incorporated with two independent, good input impedance and internally frequency compensated operational amplifiers that are carefully designed to run over a wide range of voltages from a single power supply.
  • The JRC4558 produces an output signal that is much larger than the potential difference at the input.
  • It is also applied in general-purpose operational amplifier circuits like differential amplification, comparators, and mathematical operations.
  • This device is carefully designed that requires only a 5V standard voltage supply to operate in electronics circuits. You don’t need to include an additional -5V supply to run this device.
  • Moreover, it is also employed in single supply voltage systems, amplification blocks, and transducer amplifiers.
  • This device is capable of performing two different operations at the same time as it incorporates two op-amps on board.
  • The versatility of this device makes it a good pick for analog circuits.
  • It is widely used in scientific devices and in industrial and consumer applications.
  • This device can be used individually or as a component of most complex integrated circuits.
