In case of equal voltages Uin and Ucap, the comparator outputs a signal that stops the operation of the GI. The output voltage of the DAC is fed to one of the inputs of the comparator. An example of an analog to digital converter is a Scanner It takes a picture (analog) as. The pulse generator GI generates a sequence of pulses, which are converted into binary code using the MF counter. Device used to convert analog signal into digital signal is called Analog to Digital Converter (ADC). The principle of operation of the ADC: using the method of sequential counting.

An ADC may also provide an isolated measurement such as an electronic device that. The smaller ΔU, the greater the bit width of the DACĪDC - analog-to-digital converter is a special type of encoder. In electronics, an analog-to-digital converter (ADC, A/D, or A-to-D) is a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal. Where z0, z1, z2, z3 are coefficients taking the value '0' or '1' with the corresponding key closed or open.Ĥ-bit binary code is converted to the output voltage level in the range (0 ÷ 15) ΔU, where ΔU is the quantization step. the presence of proportionality between the standard of the analog value and the code corresponding to this value in units of the lower order. Transmission error, indicating the difference between the actual and prescribed values (in the least significant units).Bit width, expressed in bits, which characterizes the measurement range of the input quantity.Thus, the capacitor-C2 is charged by the reference voltage (Vref), that through S1 and R2. The CMOS switch S1 will close circuit, at the same time S2 open circuit. While input D of FF1 is still 1 by result of IC1, so cause the output Q is also 1.
