Other Parts Discussed in Thread: OPA337 Hello,
I'm using PCM1606 with single supply. But i got huge AC noise with reference circuit as below.
We confirm the noise come from PCM1606 and LPF.
We're still working to solve the noise, but it seems…
Matthew,
OPA337 is a low voltage amplifier with the maximum supply voltage of +/-2.75V so you may not power it using +/-15V supplies.
You cannot pick the value of the feedback resistor based solely on the desired RC time constant because as Miriam…
Panlinjie,
OPA337 is specified from -40C to 85C BUT operates from -55C to 125C - see below. The difference between specified and operates lies in the fact that in the latter case the part may not meet PDS max/min specs but it works fine as an op amp…
Hi Chi-wen
Thank for your description about the difference of the boards. Is there big difference of the layout? A layout image may be help for checking the issue.
The current sense filter and trace layout will affect the funtion a lot.
On the other…

Vishal,
I am not sure what you mean by SMD IC; OPA348 is offered in three packages: SOT23-5, SC70-5 and the largest SO-8 - please see below.
No two parts are identical and you do not specify what are your most important specs in your application;…
Hi Takahiro,
an instrumentation amplifier is typically used when an unwanted common mode signal has to be removed from the wanted signal or if the wanted signal is a true differential signal. Is this the case in your application?
In most other applications…
Hi Mr John,
I have atthached the technical paper of TI from which I have devised the equation.
Kind regards

The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.
