Part Number:TLV3491
Hello,
I'm working on a design with a TLV3491AID as a simple DC comparator circuit. The supply for it is still in flux however I noticed in the datasheet for it that the absolute maximum supply voltage is 5.5V and the recommended supply voltage is also 5.5V. Is this a typo? TI's datasheets usually have a ~0.5V buffer region between the recommended max and the absolute max.
I did some quiescent current measurements with a test coupon for the op amp in my lab, which the datasheet claims an typical quiescent of 0.85uA @ 5V & 25°C. It definitely implies that the absolute max is more around the 6V territory, but I want to verify that it is true.
Here's what I measured across Vsupply (Current in uA):
- 2V - 0.7uA
- 2.5V - 0.7uA
- 3V - 0.7uA
- 3.5V - 0.7uA
- 4V - 0.7uA
- 4.5V - 0.72uA
- 5V - 0.75uA
- 5.25V - 0.75uA
- 5.5V - 0.8uA
- 5.75V - 0.8uA
- 6V - 0.8uA
- 6.25V - 1.1uA
- 6.35V - 1.4uA
- 6.5V - 2.5uA
- 6.7V - 4.5uA
- 7V - 10.8uA
Thanks!
