This circuit can cause oscillation？What is the solution?
we are using AD629, and the maximum input common mode voltage is 300V, and we need meet the reinforced insulation class, just worry about whether the IC can support that, the distance of pin 4 to Pin3 as well as pin1 to pin2 can meet this? m…
Thanks for the answer,
Basically I have 3 choices: the AD629, the TI component INA149 and the LT op-amp LT1990.
In the past I used exclusively the AD629 and probably will continue to use it.
How to design an AC voltage value with AD629 to detect about 100 Vp-p with variable frequencies
Can this circcuit do it?
Hi evryone! Please answer, what standards of electromagnetic compatibility and safety (IEC, EN…) corresponds the AD629AR?
Apologies for the delay.
Unfortunately, we do not have verified values for the CTI of the AD629. Those are only verified for our isolator parts.
I can confirm, though, that the package of the AD629 is rated at 600V. I also tracked down…
Can you tell me what is the part number of the shunt resistor that you used? If the value of the shunt resistor change due to temperature, it will reflect as gain error on the measurements.
How did you expose the parts on 60°C? May I know if…
Thank you for your interest in ADI products. The OP1177 has an operating input range of +/-13.5V for both the inverting and non-inverting pins for a supply voltage of +/-15V. That being said, I don't think the OP1177 will be able to withstand…
Since you need the full range from 0 to 130V then the AD629 architecture is the way to go.
