Hello Anshuman,
Please provide and exact schematic of the circuit you were trying to build and the resistor values used. The appnote does not provide actual values for the resistors.
Are you using the SOT or SOIC version? Please verify the SOT pinout…
Other Parts Discussed in Thread: LMP2021 , TINA-TI Hi there!
Did anybody notice that the SOT23/SC70 pinning of the LMP2021 is complete wrong?
Please look at the Pin Function Table on Page 3.
For SOT23/SC70 package the Name, Pin-Numbers, and the…
Other Parts Discussed in Thread: LMP2021 , OPA188 Hello, all
Now we are evaluating LMP2021, then would like to ask you regarding CG equation.
Please see the item below and feedback us with your comment.
On page 18 of this datasheet, it is described…
Part Number: LMP2011 Other Parts Discussed in Thread: MSPM0G1105 , LMP2021 , TINA-TI Tool/software: I'm using an LMP2011.
Even when I connect the input to ground, it still outputs about 10mV.
Please tell me how to correct the offset.
Thank you.…
Part Number: LMP2012 Other Parts Discussed in Thread: LMP2021 The LMP2012 shows a TCVIO of 0.015 μV/°C. However, figures 2 through 4 seem to conflict. If I use a vertical line for the supply or common mode, it looks like the offset voltage can vary 10uV…
Part Number: OPA376 Other Parts Discussed in Thread: LMP2021 , OPA391 , OPA396 , OPA392 , OPA325 , TLV387 , OPA387
Hi Team,
My customer uses OPA376 as differential amplifier to sample DC current.
Customer finds that the output of OPA376 drops…
Renan,
The input voltage noise spectral density graph shows the noise for the gain of 1000, which limits the effective bandwidth to BW=GBP/Gain=5kHz where it rolls off the broadband noise - see below. In the gain of 1, the noise should stay at 11nV…
Part Number: ADS7828 Other Parts Discussed in Thread: ADC78H90 , LMP2021 Hi there supporter,
We are using ADS7828 to measure the onboard voltage during runtime.
And now we have to measure an additional negative voltage rail.
Do you have any recommend…
Hello Shinu,
The LMP2012 is a chopper amplifier, so the input pin conditions are dynamic. The discussion in the LMP2021 datasheet is applicable to the LMP2012.

Note that the pspice model for the LMP2011…
Mike,
Actually, LMP2021 macro-model correctly shows the problem with Vcm=1.35V when operating on 2.7V supply but you are overlooking a disclaimer at the top of the page - Unless otherwise specified ( see below). Most of the specs are specified by default…
