ADUM3190

2.5kV rms Isolated Error Amplifier
Manufactured by:

Product Details

The ADuM3190 is an isolated error amplifier based on Analog Devices, Inc. iCoupler® technology. The ADuM3190 is ideal for linear feedback power supplies with primary side controllers enabling improvements in transient response, power density and stability as compared to commonly used optocoupler and shunt regulator solutions.

Unlike optocoupler-based solutions, which have an uncertain current-transfer-ratio over lifetime and at high temperatures, the ADuM3190 transfer function does not change over lifetime and is stable over a wide temperature range of -40°C to 125°C.

Included is a wide band operational amplifier which can be used to set up a variety of commonly used power supply loop compensation techniques. The ADuM3190 is fast enough to allow a feedback loop to react to fast transient conditions and over current conditions. Also, included is a high accuracy 1.225V reference to compare with the supply output set point.

The ADuM3190 is packaged in a small QSOP-16 package for 2.5kVrms.

Wide voltage supply is interesting for positive voltages applications. Negativ voltages doesn't covered by this Amplifier.Regrettable.

I'm currently working on a replacement for an obsolete part that I have on my product, I was trying to use an convencional amplifier but the ADuM3190 was the one that solved the problem. Noise is something hard to deal on industrial products and the ADuM3190 provided an Incredible performance, low power and I also feel confortable to work with the SSOP package. I recommend.

Worked as expected
I'm no expert by any stretch (just a high-achieving undergrad). The chip worked as expected, and was the most cost-effective product that I found Digikey. I wish it could operate with a lower common mode signal, but I guess you can't have it all. 10/10 Would buy again

Although powerful it can be given to simple uses
It is a powerful product with a wide range of possible applications. I just intended to make a simple signal buffer and found it very easy to use in that simple function
