First of all, it compares the 2 different inputs applied at the input terminal and then gives the output in digital form in order to indicate which of the input applied has a larger amplitude. It has a lot of real life applications e.g. basic comparator, driving CMOS, driving TTL, low frequency op-amp, Transducer amplifier etc. KEY FEATURES OF LM393 DUAL VOLTAGE COMPARATOR: Low input offset voltage of 5.0 mV; Low operating current of 0.4 mA; Operates from a single positive power supply of 2 to 36V; Can also operate from a split supply of ± 1.0 to ±18V; The LM393 contains two differential comparators that are completely independent other than they share a common power supply connection. It can operate on a wide.

Current sensor amplifier and over current switch project is based on ACS714-30A current sensor and LM358 Op-amp, ½ of LM358 op-amp used as an amplifier for low voltage and 2 nd 1/2 LM358 op-amp used as comparator which provides over current TTL output, trimmer potentiometer provided to set the over current limit. ACS714 sensor measures the current up to +/-30Amps, final output of the. LM358 (comparator)-1. MOC3021 (optocoupler- 1. Transistor BC548-1. Triac BT138-1. LDR (12mm)-1 . Download Gerber.dark sensor.zip. Download PCB layout 3 &4 . Photodiode darkness circuit diagram. This circuit diagram is made using the photodiode as the light sensor or dark sensor with the lm358 comparator. Highly sensitive and flicker less. Video of photodiode dark sensor circuit. As my testing. The cathode(-) of the led is connected to the source (+) terminal. Being in reverse bias, the receiver will allow, in its initial state a small current to pass through it. At the point when the IR beam falls on the receiver, it will permit a higher current to go through it. Here we will use an LM358 IC, an op-amp that we will use as a comparator

Be careful using a LM358 to switch a P-channel MOSFET, its output is only guaranteed to get to Vcc-2, which means it may not be capable of turning off some low-Vgs(th) MOSFETS. LM393 might be a better choice or a comparator with push-pull outputs. [edit] as @crutschow has just sai comparator switches from VL to VH triggering the alarm. Chaniotakis and Cory. 6.071 Spring 2006 Page 6 . Let's now consider what happens if the time evolution of the voltage Vin is as shown on Figure 11. V t t Vo V H V L ref Vin t1 t2 Figure 11 Note that as Vin exceeds Vref, the voltage at the output of the comparator switches from VL to VH and the alarm is turned on. Notice that sometime.
