Part Number: REF2025 Hi Team,
My customer is doing the BCI test (Bulk current injection), input is 100mA, 180~200MHz.
When doing this, the output of the REF2025 was not stable as it was expected to be.
Is there any test data about the BCI test or any…
Part Number: REF35 Other Parts Discussed in Thread: ADS127L21 , REF54 , REF4132 , , REF70 , REF6025 , REF2025 It is unclear to me if I need a reference buffer on the output of my voltage reference before it connects to my ADC. How do I know when I may need…
Part Number: REF2025 Other Parts Discussed in Thread: LM4132 , REF3425 Hello,
i would like to use the REF2025 on a project i am currently working on, and i would like to know if it is possible to leave the EN input pin floating. There is no specification…
Hello Munir,
Here are good replacement parts for MCP1501:
1. REF35: https://www.ti.com/product/REF35
Ultra-low quiescent current, low noise, 12 ppm/°C temperature drift
2. REF20xx: https://www.ti.com/product/REF2025
Source current ±20 mA, 8 ppm/°C temperature…
Part Number: REF2025 Hello,
We are using the REF2025 in a test fixture that gets temperature cycled as part of the test. The test fixture voltage reference is measured with a high precision DMM, then the fixture is removed and temperature cycled some…
Part Number: ADS1258-EP Other Parts Discussed in Thread: ADS1258 , REF2025 , BUF634
Hello,
1. We want to measure 16 sensors single ended with the ADS1258. The sensors are configured as a quarter bridge with the circuit taken from the TI example below. R10…

Hi all Would you mind if we ask REF2025 and LM4132 ? About initial accuracy, as time of energization passes, does this initial accuracy change? (According to passage of energization time, does accurancy value change…
Hi,
I would like to replace LT1790-2.5 on a pcb already designed.
I think I have two options:
-REF2025 but I need to know if it works with Vbias(pin 1) connected to gnd(because pin 1 in LT is gnd) and Enable(pin 3) floating.
-REF3225 if it works with…
Hi Neguse,
Yes, the REF35125 is currently in preproduction.
If you need it sooner than that, please look at using the REF2025 or REF3312 and follow the same circuit as in the REF35 data sheet.
With a shunt reference, you can use the TLV431B and flip the…
Hi Gama,
I am searching for clues or explanations.
1. Changes in Rg resistors from 249Ω to 1k Ω does not change Vout, this implies that Vout's voltage may not related to input for some unknown reasons, which it does not make much sense. Can…
