![]() ![]() ![]() ![]() In electronics we may find voltages and currents varying continuously with different ranges and magnitudes. In digital circuits the voltage signal is in two forms, either as a logic high or logic low logic levels, which represent binary values of 1 or 0. In a analog to digital converters (ADC), the input analog signal is represented as a digital magnitude, while a digital-analog converter (DAC) converts the digital magnitude back to an analog signal. How Digital-to-Analog Converters Workĭigital-to-analog conversion process can be carried out through many different techniques. ![]() One well-known method utilizes a network of resistors, known as ladder network.Ī ladder network is designed to accept inputs involving binary values typically at 0 V or Vref and delivers an output voltage equivalent to the magnitude of the binary input. The method may be understood with the following description: The output voltage is proportionate to the digital input value as expressed by the equation: The figure below demonstrates a ladder network using 4 input voltages, that represent 4 bits of digital data and a dc voltage output. The full measuring range of the counter decides the fixed time interval. #Analog to digital converter diagram full#. ![]()
