Part Number: LM4140 Hi TI engineer,
Recently I have solve a problem about LM4140(1.024V)which be proved that caused by output voltage changing when output sink current.
I'm curious about this phenomenon, so Why output voltage will change when output…
Part Number: LM4140 Hi Ti Team,
We have used LM4140ACM-1.0/NOPB part in our design to generate 1V reference voltage. We have given 5V supply as input voltage and controlling the enable signal using 2V5 level GPIO.
with 5V input supply and 2V5 enable signal…
Part Number: LM4140 Dear team,
My customer would like to increase output current for LM4140. Figure 30 on the datasheet is given for this case, but node connections looks like to be missing on the schematics. Could you please fix it?
They would like…
Part Number: LM4140 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models I'm looking for a SPICE model for the LM4140. It doesn't exist in webench5/spicemodels.

We use LM4140 for DAC REF2.5V. SCH as below. On Datasheet page9 Figure24-26 shows a Cout's ESR value range for STABLE operation.
1.We use high quality C1005X5R1A475K050BC 4.7u…
Ayodhya Weerakoon said: Recently I diagnosed that with the temperature of the IC the reading varies.
Can you give a number? Please specify how much the reading varies.
Is the voltage variation higher than the maximum temperature drift of LM4140…
Part Number: REF5020 Other Parts Discussed in Thread: LM4140 Hi Team,
Customer is using our LM4140 in there project. However, they get a VSSOP package for LM4140 by mistake. Since we don't offer a VSSOP LM4140, so they need to get a replace part for them…
Part Number: LM4140
For my application I want to change the reference voltage going to an ADC. I thought of using multiple LM4140s
One for 1024mV and the other 4096mV.
My question is if I use EN pin for this (only 1 LM4140 is enabled) task, would…
