Hi Harini,
the usual approach is to add the equivalent circuit of ADC input to the output of TLV379 and to simulate whether the OPAmp is stable with this load. Also, it should be simulated whether the TLV379 is able to settle within the aquisition time…
Part Number: TLV379 Other Parts Discussed in Thread: TLV9001 , TLV9041 Hello,
We're looking for an op amp which meets these requirements:
No phase reversal
Lowest Quiescent current possible
3V operation
Single channel
Reasonable pricing…
Part Number: TLV379 Hi, we are following https://e2e.ti.com/blogs_/archives/b/precisionhub/archive/2016/07/15/how-to-design-cost-sensitive-battery-monitoring-circuits and using TLV379 and ADC channel of NRF52832 to measure battery voltage. We already…
Part Number: TLV379 Other Parts Discussed in Thread: TLV8801 , TLV521 Hi,
If OPA as TLV379 is not powerd up, and we apply a voltage which has a 1.2V maximum to IN+ and IN-. Then what effect to OPA may produce? Can it influence the parameters of OPA…
Part Number: CC2642R Other Parts Discussed in Thread: TLV379 Hi Team,
If CC2642R's internal 12 bits ADC can support differential input?
Where can customer find some material of this function since there is no described in datasheet.
Thanks a lot…
Caro,
No, I haven't tried Kai's suggestions. I'm trying to minimize changes to the extant product, which has only 2v and 5v supplies. Also, changing the reference voltage to 500 mV limits the range of the device in a following stage. The TLV379 op amp…
Other Parts Discussed in Thread: TLV379 Hello,
The data sheet for the TLV379IDBVR, page 3, shows the drawing of the DBV package, and the table below shows a different pin out. Can you confirm which one of these is in error?

Hi Satoshi
Yes, for the U1 device in the schematic above, make sure it has input bias current low enough. Something like the TLV379 would be appropriate.
Best regards,

Hi Herman,
Thank you for your prompt reply. Using TINA TI v9, I found a basic design utilizing the TLV379 having the spice model. We have run circuit design simulations already. The results were as expected. This morning I got a nice email from Gustaf…
