Other Parts Discussed in Thread: REF3012 , REF3112 , REF3312 , REF3212 Vref is ref3012, i need 1.25V output.
when Vin is floating or 0V, ref3012 outputs 1.25V.
when Vin is 3.3V, 5V or 15V,ref3012 output 1.32V.
i want to know whether i use ref3012 right. if…
Other Parts Discussed in Thread: REF3012 Hello,
Does the REF3012 support a 1.71V input at output loads between 50-100uA?
I see conflicting notes in the datasheet that say:
Note 1, Minimum supply voltage for REF3012 is 1.8V, but then a little above that…
Other Parts Discussed in Thread: REF3012 I am using REF3012AIDBZT as a voltage reference.
The input is 3.3V but output is 1.78V instead of 1.25V.
I have checked purchasing bill, it is REF3012AIDBZT.
What is the problem?
Thanks.
Part Number: RCV420 Other Parts Discussed in Thread: TLV2333 , REF3012 Hi, I need 4-20mA input and output should be 0-3.3V. Is it possible with RCV420? Whether I need to use external circuits to bring it back from 5V to 3.3V?
Hi Gang Lin,
I could not replicate the issue on my bench.
I tested the LM4121 with load resistors between 500k to 100M Ohms and noticed no change in the output voltage.
I also sinked and sourced different currents into the LM4121 and could not replicate…
Part Number: REF3025 Other Parts Discussed in Thread: REF3012 What is the maximum capacitive load at the output of REF3025.
In the circuit are 10uF/X/R in parallel with 10nF/C0G. Is this ok?
Thanks

Hi Bob,
Thank you for your reply. You reply has generated several more questions:
1. When using the buffer, does SELFOCAL short both IN+ and IN- inputs to GND thereby violating Vin MIN Buffer ON (GND + 0.05 V) ?
2. Because I think SELFOCAL does violate…
