Do not add the DLE and ILE together to calculate the maximum error that may occur at any digital step. The maximum error values specified in the device datasheet are the worst error values measured in a laboratory test environment over the given voltage and temperature range (refer to...
A linearity of 0.2 ppm is significantly better than the 1.5 ppm linearity currently found in today’s 7.5-digit DMMs.Figure 5. INL results with the ADR1001 (100 PLC).When the ADC is set to a 62.5 kHz sampling rate, the average value register is set to 1024, the output data rate...
You have a 1.5 volt reference with a 10 bit ADC. So divide 1.5 by 1024 that gives you .00146484375. So the take the result returned by the ADC and multiply that by .00146484375. Then multiply that result by 2 (because the input to the ADC...
When using a Nyquist analog-to-digital converter (ADC) in a sampling or sub-sampling receiver application, an RF designer needs to know the ADC's effective noise figure, in order to perform determine the cascaded noise figure for the complete receiver line-up. The following discussion assumes ...
As the force is applied to the sensor, its electrical output signal can be measured, converted, and standardized. The input force can vary between load, weight, tension, compression, or pressure, and it can only be measured by a sensor that is designed to calculate that type of force. (...
Calculate KTB for B = 1Hz (equal to -174dBm at room temperature). Subtract KTB from the normalized Nyquist band noise power to determine the ADC effective noise figure. Figure 1. Steps to determine effective ADC noise figure. Observations As the sample rate is doubled, the effective noi...
Considering the relationship between torque and power, if we know the rate of rotational speed, otherwise known as the angular velocity, we can calculate power. Power is (force × distance)/time. Consider a bicycle crank arm that goes through one complete revolution in t seconds. Assume a ...
4. Sampling rate:It is the frequency at which the ADC samples the analog input, which significantly affects the accuracy of the digitized signal. This parameter is usually expressed in samples per second (SPS). According to the Nyquist theorem, the sampling rate should be at least twice the ...
determine the frequency of the signal. Also, if you sample at rate that returns the same points (same phase angle) from the waveform each time, you will not have enough data to calculate an accurate rms value. Imagine sampling a 1MHz waveform at 1 Msps. You would end up with a DC ...
This way the reading + processing should not exceed 20ms + 10ms (64 MHz Oscillator) and I will be able to trip the faulty load line within 30ms of fault. When using ADC interrupt, why not immediately process the incoming data? You have plenty of time doing this inbetween two samples...
