Selectable gain?

I hope this year’s Christmas holidays were as good as last year’s, as last year’s were obviously so good that you forgot to cancel the absence message, or were you all away for a whole year?

Hello ian0,

We sincerely apologize for the delayed response, as we are still catching up on queries (both internal and on EngineerZone) and pending tasks.

As checked, in terms of overall specification, there is no device directly similar to AD8418 with pin selectable gains of x20 and x200. But you might want to check out the following: 
- MAX49925 (w/ On-the-Fly Programmable Gain with Two Input Pins: 10V/V, 20V/V, 50V/V, 100V/V)
- MAX49918 (offers Programmable Gain Options through I2C from 10V/V to 200V/V (8 steps))
- LT6100 (w/ Pin Selectable Gains of 10, 12.5, 20, 25, 40, 50V/V)

Best regards,
Paul

Never mind - it proves you're human, but does it? I caught Claude AI not knowing what day of the week it was!

MAX49925 is excellent - does the job with the best ability to withstand overvoltage that I have seen and the price is good. Shame about the package. I could already fit 18 AD8418s in the area taken up by the shunt, I could fit 200 of these. In fact I could get 16 on the bolt head that connects the cable to the shunt. All the DFN10 package achieves is to make it difficult to prototype, difficult to test and difficult to repair, it saves no space whatsoever.
