In TVs and cell phones, digital video signals are converted into analog in order to display colors and shades. In music players, digital to analog converters can be used for generation of audio signals from digital information. The circuit that performs this is a digital to analog converter. The suitability of a digital to analog converter for a particular application is determined by several attributes such as speed and resolution.Īpplications for Digital to Analog Converters:Īn example can be found in the processing of computer data by a modem into audio-frequency tones transmitted over a telephone line. DAC architectures may contain different advantages as well as disadvantages. Due to their cost, digital to analog converters are mostly manufactured on an integrated circuit (IC). Therefore details are chosen so that errors are negligible. Converting a signal from digital to analog can degrade the signal. Signals can easily be stored and transmitted in digital form a DAC is used for the signal to be recognized by human senses or non-digital systems.

A Digital to Analog Converter, or DAC, is an electronic device that converts a digital code to an analog signal such as a voltage, current, or electric charge.

Voltage-to-frequency, staircase ramp or single slope, charge balancing or redistribution, switched capacitor, tracking, and synchro or resolverĭigital to analog converting is a process where digital signals that have a few (usually two) defined states are turned into analog signals, which have a theoretically infinite number of states.

increasing the sampling rate which increases the maximum frequency that can be measured.

increasing the resolution which improves the accuracy in measuring the amplitude of the analog signal.

There are two ways to best improve the accuracy of A/D conversion: Partitioning the reference signal range into a number of discrete quanta, then matching the input signal to the correct quantum.Īssigning a unique digital code to each quantum, then allocating the digital code to the input signal Minimum sampling rate should be at least twice the highest data.Holding signal benefits the accuracy of the A/D conversion.Microcontrollers commonly use 8, 10, 12, or 16 bit ADCs, our micro controller uses an 8 or 10 bit ADC.Some examples of ADC usage are digital volt meters, cell phone, thermocouples, and digital oscilloscope.ADC Provides a link between the analog world of transducers and the digital world of signal processing and data handling.ĪDC are used virtually everywhere where an analog signal has to be processed, stored, or transported in digital form.When signals are in digital form they are less susceptible to the deleterious effects of additive noise.Microprocessors can only perform complex processing on digitized signals. For digital computer, we refer to binary states, 0 and 1. Analog signals are directly measurable quantities.An electronic integrated circuit which transforms a signal from analog (continuous) to digital (discrete) form.
