Hello Ryker,
REF4132B25DBVR (REF4132) is a good option to replace this device if the input voltage can be less than or equal to 5.5V.
REF3425IDBVR (REF3425) is a good o ption to replace this device if the input voltage can be less than or equal to…
Hi Zhang
We have REF34-Q1 in DGK package. However it is not P2P with REF50.
Can you please comment on the existing solution from competition ?

Hello Gary,
Gary Zeng said: The device is calibrated at a constant temperature of 40°C, then shut down for one night, and then turned on the next day to keep the temperature at 40°C, and the voltage of the REF5040 becomes larger.
What is the total…
Part Number: REF70 Other Parts Discussed in Thread: REF54 , , REF35 , REF4132 , REF50 Tool/software: Can I calibrate the output of my voltage reference to increase the accuracy of my system?
Hello,
Here are some precision voltage references that could fit your requirements:
REF35 : Accuracy of ±0.05%, Options from 1.024V to 5V, input voltage range of Vout + Vdo to 6V, output current rating ±10mA
REF20 : Accuracy of ±0.05%, Options from…
Hello Kazuya,
Figure 7-4 is the typical temperature drift for either grade of REF50, not the maximum. The trend should be similar for both grades. It is meant to be used as a guideline of how the output voltage may change with temperature. For the maximum…
Hello,
There are a few options to create a current source. LM4051AIM3X-ADJ/NOPB (LM4051-N) or LM4041CEM3X-ADJ/NOPB (LM4041-N) are good options to do so. An example using one of these devices can be seen in section 3.2 of this application note:

Hi Patrick,
This is a valid configuration for some series references, however some of the series references in our portfolio have unpredictable behavior when operated in this configuration. Page 6 figure 4 of this whitepaper ( https://www.ti.com/seclit…
Hi Brian,
LM4140 is an older part. Please consider a different device such as REF35 or REF50. I have reached out to you via email for further discussion.
Thanks,

Hello,
The trim function of REF5010 is for fine tuning. It is not recommended to trim the output more than +-15mV. You can use Section 9.2 to help in choosing your resistor values.
Do you need to adjust the output voltage of REF5010? If so, what is…
