Jixia,
This FAQ has an excel calculator. I used the Reverse Thevenin sheet to give an exact answer for two resistors changing 2.5V to 1V at 100k ohms
When selecting available values for 1% resistors the output resistance was a little under 100k so I used…
Hello John,
The circuit is not a linear conversion from NTC resistance to voltage. Over a large temperature range, this will become more non linear. If your application can correct for the non linearity, then this circuit topology can be used.
I suggested…
Part Number: LMV612 Other Parts Discussed in Thread: LMV932 , LMV932-N Hi,
we are looking for alternatives to the LMV932MA/NOPB we are currently using in our boards. Looking at the datasheet we found that LMV612 is pretty much identical and I'm wondering…
Part Number: LMV612 Other Parts Discussed in Thread: LMV931-N , LMV341 1. What is the maximum value of the bias current and offset current? There are only typical values (15nA and 13nA) in the manual, and there is no maximum.
2. Does the input pin have…
Part Number: LMV612LMV612 only uses A, B is not used, but forget to process B when design, resulting in +INB, -INB, OUTB are all floating state, what will result in this, A will be invalid? The product is about to be released and does not want to modify…
We tested the new LMV612 and the results were encouraging. Please find below the oscilloscope test results conducted with the LMV612. The sound quality is just as good as previous good units, and we have achieved a maximum voltage reading of 3.33 V, which…
Part Number: LM358A Other Parts Discussed in Thread: LM358 , TLV9002 , TLV6002 , LMV612 , TLV8542 , TLV9052 , LMV358 , LMV358A Hi,
Please find the schematic, We are using LM358AD and giving 3.3V to Opamp IN+ pins, but we are getting 2.0V on output pins instead…
Part Number: LMV358 Other Parts Discussed in Thread: TLV9062 , , LMV612 Hi all,
LMV358IDR
Specsheet P11 Figure 23 shows Vo vs Vcc.
My customer want another plot. Vertical axis is same. need 1. Horizontal axis TEMP. need 2. Horizontal axis RL (Load)
Lo level…
Other Parts Discussed in Thread: TLV2442 , LMV358-N , OPA2313 , LMV612 , TLV2462A Hi,
I would like to know behavior of non-inverting circuit by LMV358-N or TLV2442.
In the following circuit configuration, output voltage will reach to 0V when the input current…
