Yes, I could do a software correlation, but the issue may be likely to change over time/devices (depending on what's causing it), so for creating multiple devices a software solution might not be appropriate :-)
Btw, please ignore my previous comment on expected performance (the "mumble, mumble...
Hello FvM,
thanks for your reply!
I see your point on input offset, I completely missed that - do you happen to know if this scales with input voltage (diff or common mode)?
But assuming it's the input offset, that means whenever someone uses this amp (A grade), they shouldn't expect better...
Hello Klaus,
thank you for your response.
Using a differential amplifier is actually a good idea if I can find sufficiently large resistors with close tolerances.
The choice of AD8428 was mainly due to low thermal drift, but that should be somewhat matchable with good resistors and a decent...
Hello,
I have an issue with the AD8428 instrumentation amplifier, that looks like common mode issue, but I might be mistaking.
Basically I drive a custom laser diode using an LT3092 current source (basically a Voltage-to-current source in my application), and use the AD8428 to measure voltage...
