Hi Jimmy,
I found and reviewed the original LOG2112 characterization data taken in 2002. The LOG2112 was not characterized for crosstalk. The description and information that you have included are applicable to dual log amplifiers, but because the LOG2112…
Other Parts Discussed in Thread: LOG112 , LOG2112 Hi, everyone,
I am trying to build a wide range logarithmic current amplifier for a scanning tunneling microscope (STM). Since the typical current setpoint is ~1nA, so being able to measure the 100pA…
Hello Thomas,
thank you for the detailed answer. I will opt for LOG2112 then. It seems to be an enhanced version of LOG104 with 2 amplifiers and a internal reference. 100 Hz bandwidth is just fine for me.
Best regards,
Dmitri
