An analog-to-digital converter (ADC) performs the reverse function. Check out the detailshereand save away!

Usually, these are removed with a low pass filter acting as a reconstruction filter in applications that require it. The voltage source is the open-circuit voltage at the cut point, and the series resistor is the equivalent open circuit resistance with all voltage sources shorted.Figure 2 below shows the locations of the cut lines well use to simplify this circuit to calculate its output impedance. This is usually related to resolution and noise floor. Resolution The number of possible output levels the DAC is designed to reproduce. DAC converters are also used as a part of the circuitry of several ADC converters. Discrete DACs would typically be extremely high speed low resolution power hungry types, as used in military radar systems. ISBN 0-7506-7907-7.
A simple 1-bit DAC is often chosen because the oversampled result is inherently linear. Advantages. There are several DAC architectures; the suitability of a DAC for a particular application is determined by six main parameters: physical size, power consumption, resolution, maximum sampling frequency, accuracy and cost. Due to the complexity and the need for precisely matched components, all but the most specialized DACs are implemented as integrated circuits (ICs). Temes, Delta-Sigma Data Converters. On the other hand, if all switches are open i.e. when ai = 1 , then bit is ON, and whenai= 0, then bit is OFF. To use the Thvenin theorem replace all voltage sources with open circuits and all current sources with short circuits - calculate the resistance looking into the port for theThvenin resistance Rth.
