Part Number: LMV844 Hi expert,
When we test Lmv844 the impendence of LMV844's IN+ pin, found that the impendence decreased with the increase of temperature when there was no power supply, Could you pls help to explain that? Thx.
Part Number: LMV844 Other Parts Discussed in Thread: OPA4340 Hi Team,
My customer would like to know footroom of LMV844 under very light load condition? Do you have any date of that?
They expects to have 10mV or more footroom in almost no load condition…
Hello Huseyin,
I am getting around the same value as you with out methods. This output impedance value from simulation is incorrect, which means this model does not capture output impedance for this device. Our newer models have a note section in marco…
Part Number: LMV841 Other Parts Discussed in Thread: LMV844 , OPA2171 , , LMV842 , TINA-TI , OPA4171 For OPA2171 you don't only provide a figure for max allowed C_LOAD and recommend R_ISO, you also provide a graph of R_ISO vs C_LOAD for phase margins…
Other Parts Discussed in Thread: LMV841 , LMV844 I am using the LMV841 (actually LMV844 quad version of LMV841) in unity gain application and I want to know if 10K in series with 4.7uF at the output would oscillate or cause some other unexpected behavior…
Hello KF,
Please see that attached Op amps - Trust but Verify pdf. The transformation from open-loop output impedance (Zo) to closed-loop output impedance (Zol) is covered in the slides.
Note that the OPA197 Zo is quite flat over a wide frequency…
