Main Types of ADC Converters Successive Approximation (SAR) ADC.
ADCs receive analog input, perform calculations on the analog signal, and then digitally encode the output in a format that computerized systems can process. What is an ADC chip?Īnalog-to-digital converter chips (ADCs) transform information from analog to digital form. Hence, flash type ADC is the fastest ADC. A 12-bit ADC converts 0 to 3.3V on its input into a digital number from 0 to 4095.įlash type Which ADC has the highest speed of data conversion?Īnalog Devices high speed A/D converters Why flash type ADC is fastest?Ī flash type ADC produces an equivalent digital output for a corresponding analog input in no time. The ADC resolution is the smallest distinguishable change in input (e.g., 3.3V/4095, which is about 0.81 mV). The ADC range is the maximum and minimum ADC input (e.g., 0 to +3.3V). For example, a 16-bit ADC has a maximum signal-to-quantization-noise ratio of 6.02 × 16 = 96.3 dB. It is a rounding error between the analog input voltage to the ADC and the output digitized value. Quantization noise is a model of quantization error introduced by quantization in the analog-to-digital conversion (ADC).
