Digital-to-analog converters (DAC) transform a digital number into a corresponding analog voltage or current

Analog-to-digital converter (ADC) chips transform information from analog to digital form

Digital-to-analog converter (DAC) chips convert digital signals that represent binary numbers into proportional analog voltages

Frequency-to-voltage converters accept a signal and convert its frequency to a corresponding analog voltage level

Scan and video converters transform a digital computer image to a standard video signal for use with broadcasting or video devices such as televisions, monitors, or VCRs or vice versa

Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.

DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems.

DC to AC inverters are used for converting direct current (DC) into alternating current (AC). They are also known as DC to AC converters.

Data acquisition computer boards are self-contained printed circuit boards that typically plug into the backplane, motherboard, or otherwise interface directly with the computer bus.

Frequency converters and translators scale and/or filter frequency inputs to produce outputs signals with frequencies that are a function of the inputs.

Voltage converters and voltage inverters accept voltage input and provide a scaled voltage output. Conversion types include scaling up a low-level signal, voltage doubling, and inversion (converting a positive voltage to negative and vice versa).

Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

Analog panel meters measure and display processes and electrical variables with a simple dial display

Analog-to-digital converters (ADC) sample an analog signal and convert it to a series of digital values to represent the signal to a computer processor
