I need to scale an IRIGB signal (+-10Vp) to my supply voltage (0-3.3V). I used AD628 (supply voltage 5V min) to scale this signal, but I don't have 5V anymore, could you give me some advice or an AD628 equivalent in 3.3V range ?
Hello. Unfortunately we do not have an AD628 spice model readily available.
However, the AD629 is on the web. That spice model coupled with an op-amp at the output for additional gain can at least give
you a reasonable replacement in terms of functionality…
I am using AD628 for my current sensing application .Current range 0 to 2.5amps through the R76 (0.01 current sense resistor ) . the gain for first stage is 0.1 and second stage is sate as 3.12 , supply voltage for the AD628 is +5V and GND (single…
I'm having trouble with a AD628 amplifier.
I have to measure a voltage between 0V and 36V using a divider bridge (see picture attached).
The AD628 power supplies are +/-5V.
With a common mode voltage between 0V and 5V, the results are very good…

Are AD628 and AD629 able to survive to a 4kV ESD pulse of 1 to 3ns at their inputs ?
Sorry for my misreading.
Fig 14 is at Gain 1 (A1 is x0.1 and A2 is x10). but scale is 100ppm but not ppm.
A1 gain error is guaranteed under 0.1%.
A total gain error will be controlled within 0.1%.
Thank you very much for your nice support…
I would like to use an AD628 to sample voltage in a 4-20mA current loop, but with a 0-3.3v output instead of the 0-5v output as depicted in the product datasheet. I'm not sure about the purpose of the 210k resistor and 2.5v voltage source, and…
