Generally, a Class D audio amplifier is a PWM amplifier or a switching amplifier. The amplifying devices in this amplifier, like transistors and generally MOSFETs, work as electronic switches but not as linear gain devices like in other amplifiers. So the switches in this type of amplifier are either completely ON or OFF to reduce the power losses within the output devices. They work by quickly switching backward and forward in between the supply rails with a PWM technique to generate a pulse … [Read more...]

This is a transmission-type photo sensor including light emitting & light receiving elements which are connected by facing each other within a single package. … [Read more...]
CD4060 IC : PinOut, Features, Specifications, Circuit, Working & Its Applications
The 4000 series CMOS logic family ICs were introduced first by RCA in 1968. These are lower-power alternatives to 7400 series TTL ICs with a binary counter & an oscillator. After that, it was migrated slowly into the 4000B buffered series in 1975. These ICs have a wider voltage supply range than the contemporary logic family. So, CD4060 IC is one of the 4000 series CMOS logic chips well-known for its high noise immunity and low power consumption. This article elaborates on the CD4060 IC, … [Read more...]
KY-033 Sensor Module : PinOut, Features, Specifications, Interfacing, Working, Datasheet & Its Applications
Sensors are significant devices that sense changes within the surroundings and change them into a signal that can be processed through a machine. So, these can detect many types of physical phenomena like heat, light, motion, sound, pressure, etc. Sensors are available everywhere around us. Likewise, a line sensor is a versatile component used for precise line tracking. This device is designed to notice and understand data from boundaries or lines within its environment. So these lines can be … [Read more...]
LM7912 IC : PinOut, Features, Specifications, Circuit,Working, Datasheet & Its Applications
A negative voltage regulator is an integrated circuit designed specifically to generate a stable negative output voltage which means the voltage is below the ground reference. So it is used where a stable negative voltage is necessary in particular audio amplifiers and op-amp circuits that require both power supplies. The main function of the negative voltage regulator is to regulate a negative incoming voltage to give a stable and lower negative output voltage, even if the input voltage varies. … [Read more...]
KY-036 Sensor Module : PinOut, Features, Specifications, Interfacing, Working, Datasheet & Its Applications
The history of a metal touch sensor mostly matches the resistive touchscreen technology development by Dr. Samuel Hurst while researching at the University of Kentucky. So it was credited with discovering the primary touch sensor in 1971, which he named the "Elograph" which is a key component in the early resistive touch screen technology. After that, this invention led to the creation of the Eurographics Corporation, which established the expansion of transparent touch panels. Metal touch … [Read more...]
NE5532 IC : PinOut, Features, Specifications, Circuit, Working, Datasheet & Its Applications
Operational amplifiers, or op-amps, play an essential role in audio systems. So, if any sound system generates noise feedback, then there are some possible solutions. Among them is a NE5532 pre-amp circuit because of its efficiency and high-quality sound. The NE5532 is a bipolar, dual monolithic and internally compensated op amp introduced in 1979 by ‘Signetics’ for audio applications. Generally, preamplifier ICs work by enhancing the input signal; thus, your audio equipment can provide better so … [Read more...]
