Part Number: REF30 Tool/software: Hi expert,
If the REF33 input current is continuously ~36mA (>datasheet recommending 25mA load current), or even higher current to damage the device, whether it will output 0 (short to GND) or become a high impedance…
Part Number: REF3040 Hi,
I'm implementing an application that requires running the MCU only on battery power in the event of a power outage (expected consumption around 25uA). The request is to use a very small battery and therefore I would like to…
Part Number: LM4040 Other Parts Discussed in Thread: REF30E Tool/software: I would like to know whether the shunt could work under 125℃.
Does the TCR keep the same?
Thanks!
Hi Mohammed
You can use a low noise precision buffer (where offset tem drift is low) buffer (opamp) to increase the drive strength.
We have released nano IQ refernce REF35 is SOT23 package, this is pin compatible with REF30. You can use it with…
Hi Tess,
I suspect that the INA828 needs the VREF pin to sink/source current. The REF30 can only source and not sink. And so when the REF30 has to sink, the voltage goes out of regulation.
Can you measure the current of the REF30 output pin?
Hi Markus
Thank you very much for pointing out Figure 7-8 and 7-18. The unit of dynamic impedance is ohm only and thereis typo in title of figure 7-18. We will change that in our data sheet revision.
We have released new reference REF35 which is pin…
Hello Brian,
I recommend looking at REF35 which is in a 6-pin SOT package as well.

REF35 replaces and provides key advantages to our older devices such as REF30 and REF33:
Ultra-low IQ of 680nA and >20% lower…
Hi
We are going to release nano IQ REF35XX. It is on ti.com and in preview.

This device offers ultra low IQ (680nA ),typical…
Hi Rock,
This is unexpected. The HBM of the REF30 is 4kV so it is less than the 6kV board test. We do not have any device above 4kV.
If you are looking for similar devices to test I would look at the REF3133 and REF3333. These are P2P and different…
