Thanks for the quick reply Mr. Vederveld;
Yes, I used an LPV821 as a diff-amp with 3.74 Gain, and a LM7705 to supply VSS so I can swing below ground to measure charge current.
And just so be double clear that my cc_gain is absolutely correct, the 100uOhm…
Part Number: LPV821 Other Parts Discussed in Thread: TLV2401 , TLV8801 , Dear,
I have no previous experience with op-amps.
I have used the TI selection tool but, to be honest, the number of parameters is overwhelming :)
During my preliminar searches, seems…
Part Number: LPV821 Dear,
I am beginning my way with LPV821. I have a sensor with 5 wires. Two of them form a NTC thermsistor. I can calculate the temp from them :) That is nice.
The other two, theoretically, polarize themselves when measuring and between…

Thanks for the details. I understood that, to apply the DC voltage to LPV821 we need this Zener diode circuit, right?
Anyway, we have an AC/DC conversion circuit and getting 3.3V that can supply the LPV821.
Below is our no neutral LED dimmer…

Hi Renan,
Please see Kai's reply about the INA333's output.
Regarding to the input stage, here is an example.
INA333 + 24bit ADC 07182022.TSC
Since you are selecting 2.5Vbandgap reference, OPA387 may be acceptable. If you select Vbg of 1.25Vref…
Hi Jimmy,
I checked with op amp cross reference tools and did not find the direct recommendation. However, the TLV8811 or TLV8812 looks like a good replacement, and it is currently in stock.
Enclosed are additional recommendation that may work for your…
Part Number: LPV812 Other Parts Discussed in Thread: LPV821 , LPV811 , TLV2333 , LM358 , OPA627 I happen to have a design where the same input voltage is amplified with an inverting and a non-inverting amplifier (with similar gain actually).
The offset voltage…
