Part Number: LMC6082 Other Parts Discussed in Thread: LMP91000 , LMC6081 , , LMC6482 , LMP2232 , LMC6492 Dear Forum,
I am currently trying to design a dissolved oxygen device using a 2-wire polarographic probe. The max output of this probe is roughly 40-80…
Part Number: LMP2012 Other Parts Discussed in Thread: LMC6081 Quick questions: is LMP2012 is fully Bi-polar technology or if it is part CMOS technology. Let me know, thanks!
Hi John,
LMC6001 and LMP7721 are the two lowest Ib options we have. A lower cost option might be LMC6081, with a 100fA input bias current. While LMC6001 and LMC6081 both share a common pinout, LMP7721 has a different pinout (and is only available in SOIC…
Hi Hojart,
if you have an Arduino with ATMEGA328 and want to directly drive the ADC input, you could use the following circuit:
Corner frequency of low pass filtering is about 150Hz. If you need an OPAmp with lower input offset voltage, take the LMC6081…
Ron:
I think I need tell U my solution.
When I check my LMC6001, I find mark on this chip is NS not TI. So maybe this is an old product or fake one. Cause I haven't a new one at hand. So I use LM358 to test this circuit. And It worked well. …
Hi Eric,
If 5V is too low and can go up to 15V supply, I would also recommend the LMC6001 (tested to 25fA) or LMC6081 (parent die of LMC6001 and still typically <20fA). Or the LMC6482 if you need R-R input (also typically <20fA).
Hello Peng,
The LMC6001 is based off the LMC6081, with layout improvements to improve bias current yield.
The LMC6041 is the micropower version of the LMC6081, so the noise will be higher since micro-power parts are noisier than their "normal" power counterparts…
Hello,
There is not a direct replacement for the OPA317 in a PDIP package. Some other devices that would work in this application and are available in the PDIP package include the OPA340, OPA344, and LMC6081.
Other Parts Discussed in Thread: LMC662 , LMC6081 I'm seeking clarification on a note within the PSpice model provided for the LMC662 opamp. Specifically, there is a note within the PSpice model that "Asymmetrical gain is not modeled" and I'm not sure…
Other Parts Discussed in Thread: LMC6041 , OPA381 , LMC6061 , LMC6081 , LMC7101 , LMC6482 Hi,
I am trying to sense the current from our chip by using transimpedance amplifier. And we have the -5V to +5V power supply option on our PCB board.
The current range…
