Da dodam i ovaj link za TI-ov "trening" u 16 delova oko teme merenja struje.
Vrlo lepo i sazeto su kompletno prosli problematitiku merenja struje sa objasnjenjem svim mogucih izvora greske.
Kad budete odgledali zacudicete se koliko je to problematicno i koliko greska moze da bude velika, cak 40 do 100%!!! ... kad stignu do 1% greske u celom opsegu to je u laboratoriji "pice za sve"

The Basics
Session 1: When to choose a Current Sense Amp
Session 2: Current Sense Amp Design Considerations
Session 3: Implementation options for both high-side and low-side monitoring
Session 4: How to choose an appropriate Shunt Resistor
Understanding Error Sources
Session 5: Understanding different types of error in current shunt monitor designs
Session 6: Understanding gain errors
Session 7: Understanding offset errors
Session 8: Understanding filter related error
Session 9: Understanding common mode voltage error
Session 10: Understanding temperature related error
Session 11: Understanding power supply rejection error
Session 12: Understanding shunt resistor tolerance error
Advanced Topics
Session 13: Layout considerations for a Current Shunt Monitor circuit
Session 14: Debugging a Current Shunt Monitor circuit - where to probe
Session 15: Programming Power Setting
Session 16: Benefits of Integrated Precision Shunt Resistor
