An audio preamplifier or preamp is one type of electronic amplifier, used to change a weak input signal into a strong output signal used for a loudspeaker & a power amplifier. These amplifiers are normally used for amplifying analog sensor signals like microphones & pickups. So, this is frequently arranged very close to the analog sensor to decrease the noise & interference effects. There are different op-amps are used in audio pre-amplifier circuits like NE5532, LM258, TL072, … [Read more...]
ULN2003 MotorDriver IC : PinOut, Specifications, Interfacing & Its Applications
A motor driver IC is an essential component used in controlling motors within autonomous robots. These integrated circuits work as an interface between microprocessors & the motors within robots, so these are frequently used to drive DC motors in robotics from microcontrollers. The main reason to use Motor Driver IC in different applications is; most microprocessors work at low voltages & use low current whereas the motors need a relatively high voltage as well as current thus, the … [Read more...]
TB6600 Stepper Motor Driver : Pin Configuration, Interface with Arduino, Working & Its Applications
Stepper motor drivers are small pin-compatible modules designed particularly to drive stepper motors capable of continuously rotating with precise position control without the need for a feedback system. The stepper motor drivers have built-in converters that offer multi-stage resolution and variable current control that allows control of stepper motors with simple step and direction inputs. These modules are usually the main carrier boards for various stepper driver ICs that provide low-level … [Read more...]
MX1508 DC Motor Driver : Pin Configuration & Its Applications
When a conventional geared DC motor is connected directly to the output of the ICs such as Atmega16, microcontrollers, 555 timers, and 74 series ICs the motor might get damaged. Because these ICs cannot provide at least 250mA of current required for the DC motor. Therefore, to drive the DC motor, a circuit (with transistors or relays or L293D/L298) is needed that can work as a bridge between the motor and the IC. Hence, the manufacturers and hobbyists use several IC motor driver modules in … [Read more...]
What is 555 Timer IC – Working with Operating Modes
The IC 555 timer was invented by “Signetic Corporation” and it was termed as SE or NE555 timer. Generally, it is a monolithic timing circuit that gives precise and highly stable delays of time or oscillation. These types of ICs are very cheap and reliable in cost when we compared with the OP-Amp applications in the same areas. These ICs are used as an astable and monostable multivibrators in digital logic probes, DC-DC converters, tachometers, analog frequency meters, voltage regulators, … [Read more...]
What is a Comparator – Types & Its Working
Comparators are classified into various kinds, such as electronic, electrical, mechanical, optical, sigma, digital and pneumatic comparators, these are used in various applications. Comparators play an essential role in designing electrical and electronic projects. In electronic circuits, an op-amp is used with negative feedback and it can also be used as a comparator. The comparator is mainly designed without feedback for open loop configuration. These are widely used in A/D converters. When … [Read more...]
