as you can see in the picture below in the datasheet of the XTR111 it says that the minimum current output of the integrated…
Part Number: OPA3S328EVM Other Parts Discussed in Thread: OPA3S328 , TINA-TI , ADS1675 , LMP7721 , LMP7715
Hello Experts,
Our customer has a technical question about the product OPA3S328EVM.
He has been going through the "Application Report: Build a Programmable…
Hi Ben,
I contacted the PGA280's designer and we still do not have the data to answer your questions directly.
Per PGA280's Mux input block, ESD diodes are before the mux switches and there are always a few on/off switches connected to the input…
And along these same lines, I was looking at this relatively new switched gain device the OPA3s328, these equations are correct where that one for Cf has that 4 in the denominator instead of 2. The extra 2 in the square root is essentially setting the…
Part Number: LMP7707 Other Parts Discussed in Thread: IVC102 , LMP7721 , OPA328 , OPA928 , OPA3S328 , OPA320 , STRIKE Hi
Using your op amp LMP7707 to build an integral circuit to integrate the photodiode output current signal, PD is a photovoltaic mode zero…
I just received additional information from the customer:
I saw a couple other options that are more oriented toward our voltage requirements where 2.7V or less operating voltage range is better. Also, we are just trying to capture a laser detection of…
There is no easy way to measure 1nA change with 250ohm TIA as this implies 250nV resolution - see below.
Changing the input current by 1nA from 1mA to 1.000,001mA would require resolution way below the input voltage noise of LMP7721. Simulating the input…
Part Number: OPA859 Other Parts Discussed in Thread: TMUX136 , OPA3S328 , OPA3S2859-EP , LMH32401 , OPA3S2859 Hi,
This is very similar to the question posted in the forum

Hello Javier,
From the Precision Amplifier team, we have several devices that can be used as a TIA. I'll assume at the moment you have a low voltage, isolated, floating supply, for which I will recommend a few low-voltage amplifiers that can work well…
HI Jeremy,
Please see below the OPA3S328 configured on a programmable gain amplifier configuration.
The OPA3S328 input impedance is high since it is intended for transimpedance amplifier applications (but not as high as the ultra low leakage LMP7721 or…
