What is LM293?
LM-293 is a dual independent accurate voltage comparator. LM 293 has a capability to perform its operation from a single supply source as well as from split power supply. The purpose to design LM-293 is to permit a common mode range to the ground level and it perform this operation with single power supply source.
What is the difference between LM393 and LM358?
LM393 Comparator Introduction The LM393 IC can be considered as the equivalent comparator version of the most popular LM358 Op-Amp. While any Op-Amp can be made to work as a voltage comparator, the LM393 proves itself to be advantages by providing an open collector output making it suitable to drive loads.
What is comparator circuit?
A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.
What is a dual differential comparator?
Texas Instruments LM2903-Q1 Dual Differential Comparator consists of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Current drain is independent of the supply voltage.
What is an L293D?
The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high current / high voltage loads in positive supply applications.
What is the function of LM358?
LM358 can be used as transducer amplifier, DC gain block etc. It has large dc voltage gain of 100dB. This IC can be operated on wide range of power supply from 3V to 32V for single power supply or from ±1.5V to ±16V for dual power supply and it also support large output voltage swing.
What is LM393 used for?
The LM393 IC is a low-power, single-supply, low-offset voltage, double, differential comparators. Generally, a common comparator IC is a tiny voltmeter by included switches. It is used to calculate the voltages at two dissimilar terminals and contrasts the dissimilarity in voltage quantity.
What type of circuit do comparators use?
Op-amp window comparators are a type of voltage comparator circuit which uses two op-amp comparators to produce a two-state output that indicates whether or not the input voltage is within a particular range or window of values by using two reference voltages. An upper reference voltage and a lower reference voltage.
Why is comparator needed?
Comparators are used to find-out deviation of dimensions between a given component being checked and a known datum. The indicated difference in the dimensions is usually small and hence suitable magnification device should be employed to obtain the desired accuracy of measurements.
