App note: Pitfalls of trusting the datasheet

Posted on Sunday, September 30th, 2012 in app notes by DP

Analog Devices explains when the maximum supply current given by the datasheet could lead you astray:

For most integrated circuits, a maximum supply current is listed on the data sheet. Often overlooked are the measurement conditions. For some rail-to-rail output op amps, certain operation can result in supply currents two to ten times higher than the stated maximum. Whether bipolar or CMOS, some tips are given as to what to look for to see whether or not this is a concern.

  • KH: After reading all the comments, I have questions: Does this mean STM32 and AVR boards/parts from dodgy online sellers are suspect? What are your opinions?...
  • Sjaak: They are available with more flash then their ST counterparts which makes them more interesting. You don't have to port the code, but use another...
