Part Number: OPA836 Other Parts Discussed in Thread: OPA838 , , OPA837 Hi team,
My customer is using our OPA836 & OPA838 now.
And they wonder if we have a newer device to recommend.
Requirements:
BW: >200MHz
slew rate:>200V/us
Iq:<1mA

Part Number: OPA188 Other Parts Discussed in Thread: OPA838 Hi,
in general voltage amplifying circuit, it's clear to calculate the closed loop bandwidth to be GBW/gain.
But if I configure a OPA188 as a current to voltage circuit(TIA). How can I calculate…

Part Number: EVM430-FR6047 Other Parts Discussed in Thread: OPA838 , EVM430-FR6043 I have a couple of questions but first I wanted to start with a description of the goal of the project. Currently we are trying to make a flow detector. Ideally, we would…
Hi eDesign ,
Thanks for the inputs. Are you looking for required bandwidth of 15MHz or max signal frequency is 15MHz?
As you saw in the previous e2e post, you can use LMH6624 if max signal frequency is 15MHz and you need a gain of 40dB. However, given…
Other Parts Discussed in Thread: OPA838 , OPA3S328 , OPA3S2859 Hi, support team
My customer has the questions as follow:
I am looking for an opamp which has high input bandwidth used with a gas sensor, which has 60nA to 0.2mA output current need…
you also need to think about gain bandwidth product.
at a gain of 150, the OPA838 is about 2MHz BW, the OPA189 will be far lower.
The OPA838 is pretty good offset voltage wise, but you said 100Hz min, AC couple the gain then to reduce the DC gain…
Hi Leo,
Thank you for pointing out OPA838, have not seen that one before!
In your application note on Figure 2 you have the lowpass again.
I will give a few resistor values a test.
Best regards,

I was going to use this table in an article discussing max linear output current - might be a few errors here, this is in the 5V table,
1. Perhaps the overtemp output voltage swings…
Morning Poh,
You should look at the OPA838,
However you will need to add a cap on the inverting node to ground perhaps for stability, Also your R values need to come down a little if you care about noise.
Here is a design that looks promising, …
