I am running a square wave (29Hz, approx 1.2Vpp centered at 2.5V) across a current sense resistor which is used in conjunction with the INA214. Power supply to the INA214 is 5VDC.
I am getting a 1V spike at the rising edge of the square wave that needs to be suppressed. Here is a relevant portion of the circuit:
In the image below, you are looking at pin U5B-5 and you will note the transient along with some signal (elevated signature during positive clock).
I have tried 10 ohms with capacitance tied to ground at the input pins of U8. As capacitance increases to 1uF, transient moves from positive edge of clock to negative edge. I also tried configuration of Figure 24 from the datasheet, but with no success eliminating the problem. I tried to lower the value of the current sense resistor to 0.1 ohm and that also had no impact to performance.
