Part Number: LMH6551 Hello,
I am trying to design a highly sensitive transimpedance amplifier (TIA) system to amplify very low modulated current levels of a photodiode (order of ~10 nA peak-to-peak). This is my first time simulating/designing an analog…

Hi Sneha,
I was able to look into our devices and simulated a few with the +/- 3.3V supplies and 500V/V requirement and the biggest problem is the lack of head room. As for a potential device, the THS4561 will be the best device in terms of voltage offset…
Michael,
There are many different possibilities for this issue. Having more detail on how large the current load is, and the detailed schematic with the two amplifiers would help me to give a more precise answer. Here are a few possibilities.
It is possible…
Part Number: THS4541 Other Parts Discussed in Thread: ADS8881 , , THS4551 , THS2630 Hi TI expert ,
I am designing a MFB band pass filter for 18bit ADC( ADS8881), the center frequency of BPF is 1kHz, Q = 4, gain = 1, pass bandwidth = 250Hz, stop bandwidth…
Well John, couple of easy comments and cautions, The THS4531A is the better DC offset version, here is an old spec comparison I found - the THS4561 is probably a better part, but 3X the Icc. But the faster THS4561 might be able to do the entire gain in…
Camille,
The pocket reference is the engineering definition document and not a product catalog. We don't really have a product catalog anymore. The closest to a "catalog" would be to use the parametric search to find a device that matches your requirements…

Hi Mareks,
Thanks for your quick response and suggestion on the precision amplifier. I have the following further queries:
Can OPA191 use straight away as a unity gain buffer for a 10uV low-level signal? Do we need to add any offset removal circuit in…
Hi Behnam,
One critical thing to note about the OPA838 is that the absolute maximum supply voltage rating is 5.5V and so setting the supply voltage of +/-3V is exceeding this range. Also, setting the supply voltage at +/-1V might not be turning the op…
