Part Number: TLV8812 Other Parts Discussed in Thread: TLV7031 , LPV812 , LPV7215 Please help recommend a suitable replacement material of TLV8812 and TLV7031, thanks.
Hi Hari,
the TINA-TI DC analysis shows VF2 = 3.998994V and VF3 = 3.99899V. VF2 - VF3 = 4µV.
This error voltage is the sum of the finite CMRR, the input offset voltage and the open loop gain of LPV812. Have a look at this very simplified calculation…

Don’t be too worried about bias current slightly below ground unless you are forcing it below the standard offset voltage range. We’ve got several customers using these parts at a common mode of 0v for their 2 wire gas sensing applications. In…
Hello Kai,
Please check the following nanpower dual channel devices; LPV542, LPV802, LPV812, TLV8802 and TLV522.
For a complete list of TI's nanpower opamps please check the link below.

Alessio,
I checked the data sheet for low current duals (in order) LPV802, LPV812, TLV8542, TLV8802, TLV8812, TLV522 , LPV542, TLV2402 OPA2369, LMC6442, TLV2369, and OPA2349. You can check higher ICC devices yourself if you like, but suspect over 30…
And, I think I finished scanning the TI product trees for post 2015 <50MHz Introductions - omg, this is quite impressive, lot of work here to fill in the parametric fields, but this is the list I came up with the slightly modified descriptions - this…
