Part Number: LAUNCHXL-F28379D Other Parts Discussed in Thread: OPA350
This may be a more general question for the amplifiers team, but it concerns something I have always been confused about regarding the ADC voltage buffers on the Launchpad.
They…
Part Number: OPA350 Other Parts Discussed in Thread: OPA656 Hi team,
Here is a confusing item of OPA350 current noise spectral density curve.
As OPA350 datasheet show:
So why the current curve performance is as above current noise spectral curve…
Part Number: OPA350 Other Parts Discussed in Thread: LM7705 Hi. I am referring to the following remark in the forum (Sep 7, 2017) about using an OPA350 in a photodiode transimpedance amplifier:
"Also, please be aware that since OPA350 output can only…
Part Number: OPA350 Other Parts Discussed in Thread: TMS320F2837 , My customer is basing a design off of a voltage reference circuit that is in the TI Delfino Launchpad. See circuit below from sprui77c.pdf . What criteria were used in the selection of…
Part Number: OPA350 Hi, a few questions regarding using OPA350, thanks!
1. is there any concern to use OPA350 for current sensing amplifier for a DCDC converter as shown below. OPA350 datasheet typical application doesn't include current sensing amplifier…
Part Number: OPA350 Other Parts Discussed in Thread: TLV9061 , OPA320 , OPA325 , LMP7731 Dear TI team,
Good evening.
We are using OPA350 in sensing circuits in grid tie inverter.
In our sensing circuit,we are using differential isolation opamp and…
Hi Marek,
Sorry for my late reply.
I understand about the 2nd picture.
Blue is the waveform of the current which is through sense resister (0.01, 0.02ohm). (Please ignore green and yellow). Blue is came from motor and the peak current is 7.45A and…
Part Number: OPA350 Other Parts Discussed in Thread: OP27 , OPA827 , OPA627 Hi Team,
Customer is asking if this device has any warm up time requirement so can meet our accuracy/drift spec? Thanks!

Hi Alessio,
Thanks Kai for providing the simulation and suggestion.
Q: I cannot find it in OPAx350 datasheet, where instead a 1 kohm value is given at low frequency (section 7.3.6). What is the correct value?
I think that the statement from the…
Part Number: OPA350 Hello all,
I am trying to use the OPA350PA and take advantage of its low input bias current to amplify a small signal of around a nA of current. I have it set up in a simple negative feedback loop with a resistance value of 100 mega…
