Hello Luis,
There is a document that is to be published tomorrow (TIPD135) that provides a solution similar to your question. Please try searching www.ti.com for TIPD135 tomorrow morning.
I noted that it is a similar solution, but there should be…
Hello Nikos,
1. The datasheet was written over 40 years ago...I don't know if it was actually built...the original authors are long gone. But it is a common circuit.
2. Assumptions were probably a large current .The LM324 is not considered a "precision…
Hello Mayer,
For such a large range of input current I recommend evaluating a PGA. Please take a look at the following TI Precision Design:

This design describes a 10uA-100mA current sensing solution (high side), but…
Vineet,
With a current shunt monitor is going to be difficult to measure such small currents. Please see the current shunt monitor FAQ ( ) a few TI Designs that may work for your application, and I'm going to move your post to the precision amplifiers…
There are several error sources to consider when sensing current (or using amplifiers in general) such as CMR, PSR, noise, gain error, and voltage offset drift, but two device properties (input bias current (I B ) and input offset voltage (V OS ) ) are…
