A Hex inverter IC is a type of chip that includes six inverters within a single package. So, every inverter in this IC has a single input and output which performs the logical inversion operation. This IC is used for signal inversion, conversion of logic level & CLK signal generation within digital electronics. These inverter ICs are found easily in most electronic devices that produce data in small circuits. Examples of hex inverter ICs are CD4069 IC, M74HC04, and 74HCT04. So, this article … [Read more...]

Audio amplifier ICs are electronic devices that increase the audio signal strength by enhancing sound quality. So these ICs are used in various audio devices like portable speakers, stereo systems, home theaters, smartphones, etc. Audio amplifier ICs work in audio systems by using a small audio input signal to increase power to drive headphones or speakers to generate sound. Different letter symbols like Class A, B, C, Class D, and AB categorize these integrated circuits. So these ICs are … [Read more...]

An audio power amplifier is an electronic amplifier, used to amplify low-power electronic audio signals, signal from the receiver of a radio to a certain level that is high sufficient to drive headphones or loudspeakers. There are different integrated circuits used in making simple as well as cost effective based audio amplifier circuits. Similarly, monolithic IC like TBA810 IC is used to make 7-watt audio amplifier circuits and is most suitable for designing low-power audio amplifiers. This … [Read more...]

PWM controller is a fixed frequency control and very simple integrated circuit, used for controlling nearly any power topology like boost, flyback converter, buck, forward, push-pull, etc. There are many manufacturers which provide high-performing PWM controllers like general-purpose & application-specific. These controllers provide flexibility for covering a wide range of power-supply designs which are utilized within AC-to-DC and DC-to-DC power-conversion circuits for different equipment. … [Read more...]

An optocoupler also called photocoupler or optoisolator, is an electronic device used to transmit an electrical signal between isolated circuits by separate grounds for providing an isolated galvanic wall between them. So, an optocoupler is appropriate for some circuits that need to be separated from each other for security or reliability reasons. Optocouplers are very helpful in removing noise from signals, avoiding distractions from voltage surges, and also separate low-voltage-based devices … [Read more...]

A DAC (Digital to analog converter) is a type of integrated circuit that changes the signals from digital form into analog. This IC plays a key role in an audio player for converting the audio signal from digital to audio that can be played throughout a speaker. Digital-to-analog converter ICs are frequently used in TVs, music players, and mobile phones for converting digital video data into analog video signals. The audio DAC type IC is a high-resolution & low-frequency type whereas the … [Read more...]

An electric motor is a more frequently used actuator in any machine or electronic device which is used from a vibration motor within mobiles to stepper motors within CNC machines. These motors' motion & direction can be controlled through a motor controller or motor driver using a processor or microcontroller. The motor driver output is in digital form thus it uses pulse width modulation for controlling the motor. There are different types of motor driver ICs available in different sizes and … [Read more...]
