3/26/2023 0 Comments Trigger pin on the lm358 as timer![]() No pull-up resistor is required at the output of LM358. Similarly, when the input at Non-inverting Input B (+) at pin 5 is less than the input at Inverting Input B (-) at pin 6, the output of op-amp B will also be low. On the other hand, when the input at Non-inverting Input A (+) at pin 3 is less than the input at Inverting Input A (-) at pin 2, the output of op Amp A will be low. Similarly, When the input at Non-inverting Input B (+) at pin 5 is greater than the input at Inverting Input B (-) at pin 6, the output of op-amp B will also be high. ![]() When the input at Non-inverting input A (+) at pin 3 is greater than the input at Inverting input A (-) at pin 2, the output of op-amp A will be high. The voltage of pin 2 will be compared with that of pin 3, and the voltage of pin 6 is compared with that of pin 5, corresponding to two independent outputs: Output A and Output B. If we want to use the second amplifier (B), then the input for this amplifier is at pins 5 and 6 and the output is at pin 7.įor the comparison of two signals, we will give one signal at pin 2 and the other signal at pin 3. LM358 contains two operation amplifiers (A&B as in the pin diagram) where the input of the first amplifier (A) is pin 2 and pin 3 and the output is pin 1. If we want to use the LM358 as an operational amplifier then we will give the supply voltage from ☑.5V to ☑6V. If we want to use LM358 as a comparator, we can give input voltage from 3V to 32V. In LM358, Pin 8 is the main power supply input. Pin1 and pin8 are the output of the comparatorĪll the pins of LM358 IC along with their sequence number are given in the tabular diagram shown below.The real image and pinout of the configuration of LM358 IC is shown in the diagram below which has eight pins in total having different individual functions associated with each of them. Available packages are TO-99, CDIP, DSBGA, SOIC, PDIP, DSBGA.Operating ambient temperature range is 0˚C to 70˚C.Input common-mode voltage range includes ground.Internally frequency compensated for unity gain.Differential input voltage range is similar to the power supply voltage.The large voltage gain is around 100 dB.Integrated with two operational amplifiers in a single package.Some important features and specifications of LM358 IC are as follows: ![]() Some of these components have identical pinout and package sizes to allow for compatibility between different manufacturers. You can go through the Op-Amp IC 741 to learn more about the operational amplifier.ĭepending upon the manufacturer, each product may have a slightly different variation of the components and each has very similar specifications. In this guide, we will learn about the Dual Op-Amp LM358 basics, characteristics, circuits, working, pins configuration & Applications. LM358 IC can handle 3V- 32V DC supply and source up to 20 mA per channel. ![]() LM358 is available in a cheap-sized package so it is widely used in real-life applications including transducer amplifier, DC gain block, active filter, and conventional op-amp circuit design. It is more flexible for low voltage AC and moderate voltage DC applications. LM358 is specially designed to operate from a single supply over a wide range of voltage. It consists of two independent compensated operational amplifiers with low power and high gain frequency. ![]() LM358 IC is a dual operational amplifier integrated circuit with two Op-Amp powered by a common power supply. ![]()
