What do you mean by resolution in ADC and DAC?

What do you mean by resolution in ADC and DAC?

Resolution. The resolution of a DAC is given by the number of bits, N. The resolution is the smallest increment of output that the DAC can produce. An 8-bit, DAC has a resolution of 8 bits, or one part in 28.

What is meant by ADC?

Analog-to-digital converters, abbreviated as “ADCs,” work to convert analog (continuous, infinitely variable) signals to digital (discrete-time, discrete-amplitude) signals. In more practical terms, an ADC converts an analog input, such as a microphone collecting sound, into a digital signal.

What is ADC size?

ADC has a resolution of one part in 4,096, where 212 = 4,096. Thus, a 12-bit ADC with a maximum input of 10 VDC can resolve the measurement into 10 VDC/4096 = 0.00244 VDC = 2.44 mV. Similarly, for the same 0 to 10 VDC range, a 16-bit ADC resolution is 10/216 = 10/65,536 = 0.153 mV.

How to calculate resolution of ADC?

The resolution defines the smallest voltage change that can be measured by the ADC. As mentioned earlier, the resolution is the same as the smallest step size, and can be calculated by dividing the reference voltage by the number of possible conversion values.

What is an ADC used for?

The ADC is used to convert an analogue input signal (an analogue voltage within a specific range) to a corresponding digital data that can be processed and used by the PIC.

What is the purpose of ADC?

It performs a coarse conversion. It then compares that conversion to the input signal. The ADC performs a finer conversion, allowing for an interim conversion of a range of bits.

What is the resolution of DAC and ADC?

Resolution (ADC) is the degree to which nearly equal values of the analog input quantity can be discriminated. Resolution (DAC) is the degree to which nearly equal values of the analog output quantity can be produced. Analog resolution (ADC/DAC) is the nominal value of the step width/height.
