Ok, so what is the correct way of doing it?
My constraints on Rsense are:
A) Power Consumption
B) Rail tolerance
C) Max / Min Vsense scale -> ADC to maximize dynamic range.
I had assumed it would be better to crank the gain up on the amp, as long as I didn't saturate the ADC.
Are you...
I didn't see that table.. thanks.
Can I use that amp as a current output device (rather than sticking the resistor on the output), and connect it to current-input ADC, such as: http://www.ti.com/lit/ds/symlink/ddc232.pdf ?
What are the pro/cons of doing that versus using it in that manner...
Yeah, that's what I figured as well. I think I'm going to get the high gain version of the 9934, and scale the shunts accordingly. I figure I'll get a better SNR that way.
By the way, why doesn't the datasheet speak in terms of gain, rather than saying "25uA/mV" or whatever? Since the input is...
Hi all,
I'm trying to integrate some current sensing into a project. I've got about 20 shunt resistors that I want to use to measure current into various portions of my circuitry.
Now, my plan is to create a daughterboard that can be attached to the mainboard to measure these currents. The...
Hello everyone,
Quick question:
I'm spec'ing a transformer to take an input of 277V Delta, and to output 480V Wye. Please see the attached photo, and tell me if I've made the correct choice :)
One confusion I have is that the specs show the Sec. Voltage as 208Y/120 -- I assume this is for the...
