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
Hello,
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…
Part Number: LM4140 I'm using the LM4140 ACM -1.0 as a voltage reference for some current shunt amplifiers and the ADC converter.
Input voltage is 3.3V(from an TLV70033 LDO with a 10uF cap output and threw a ferried bead, this rail is clean), input…
Part Number: LM4140 Other Parts Discussed in Thread: LM4040 Hello, I'm looking to build an interface circuit for a temperature sensor, probably a thermocouple with a 1k or 10kohm resistor.
I found this application note:
regarding the use of this voltage…
Dear Alone173 -
I would also add here to Raymond's input this reference design using the LMP7721 & LM4140 (precision reference you were looking for, too): https://www.ti.com/lit/an/snoa529a/snoa529a.pdf
then compare to this reference design, using…
Part Number: LM4140 Other Parts Discussed in Thread: TL431 Although customer want to make 7.5Vin to 3.8Vout for LM4041CEM3X-ADJ, attached simulation results was less than 2Vout.
I think that current is enough (IRMIN(max.)<60uA), but actual measure was less…
Hi Ayodhya,
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…
Other Parts Discussed in Thread: LM4140 Dear e2e,
in the Datasheet for the LM4140 it states:
=======================================
The LM4140 is available in three grades (A, B, C) with 0.1% initial accuracy and 3, 6 and 10 ppm/°C temperature coefficients…
Hi,
I apologize that no one has followed up with your question. I'm going to close this thread, but if you still have a question please feel free to post a brand new thread instead of replying to this one. We will do our very best to respond within…
Part Number: ADC128D818 Other Parts Discussed in Thread: LM4140 Datasheet question regarding bypass caps for the adc128d818 VREF - in the adc128d818 datasheet it states
1) on page 4 it states "ADC128D818 allows two choices for sourcing VREF: internal or…
