#### 1-1. What's the sampling frequency of the device? Delta-sigma frontend at 500kHz (±30%) Transients that occur at or very close to the sampling rate's harmonics can cause problems (1Mhz and above). These can be filtered with some RC filtering at the input. ![[Pasted image 20250228082644.png]] #### 1-2. What is the maximum frequency of signal that can theoretically be measured? Since the sampling rate is listed at 500kHz, so my first thought is the Nyquist rate at half that (250kHz), but there's also a Conversion Time table that indicates it resolves the final data points much slower (84us -> 12kHz). So I'd say 6kHz is the upper limit before distortion/aliasing. ![[Pasted image 20250228083456.png]] #### 2. Would you use this device to measure a signal of 5-50kHz if you didn't know what the frequency content was? Seems unwise #### 3. How should the traces be connected to the shunt resistor? (draw footprint for a SMD shunt). Why? What would happen if it were not connected this way? It recommends a kelvin/4wire connection to ensure the shunt resistor is the only impedance being measured. Otherwise you get additional trace/lead resistance in the measurement that skews it. ![[Pasted image 20250228084627.png]]
