Introduction
Hello TI Engineers and Community,
I am a lab technician working in a chemical biology lab, where I dabble in using embedded systems for…
Hi Jack,
I assumed that you have read the following article.
https://www.ti.com/lit/wp/sboa586/sboa586.pdf
Per your description, the LPF's cutoff frequency is very low at 15.9Hz, and you are likely concerned about 1/f noise, not the broadband noise.…
Part Number: ADS1299EEGFE-PDK Other Parts Discussed in Thread: OPA387 , OPA350 , OPA378 Tool/software: Previous thread link isn't working, it will be very helpful if someone can point me in right direction. Thanks.
Part Number: OPA2387 Other Parts Discussed in Thread: OPA387 , ADS1299 , OPA397 , OPA2392 , OPA2376 , OPA2391 , TLV2376 Tool/software: Hello,
we are designing a EEG Device ,where the device is suitable for EEG device as pre amplifier in AFE. And also please…
Hi Chandra,
Thanks for the additional information. I do recommend an additional ADC driver stage for your circuit. For a 16-bits @1MSPS I recommend OPA388 for its wide (10MHz) bandwidth. OPA388 is a zero-drift, zero-crossover, rail-to-rail input and output…
Hi Stefan,
Both OPA387 (5 MHz) and OPA388 (10 MHz) are MUX-friendly, they both use a similar switching architecture at the front end as OPA189. For lowest noise, OPA388 is the best choice, but for lower power, OPA387 is the best.
Let me know if there…
Part Number: ADS1114 Other Parts Discussed in Thread: OPA387 , I have an ADS1114 receiving an input signal between 0V - 4V, the signal goes through an OPA387 set up as a buffer, just before the A0 input of the ADC i have a low pass filter for 80hz made…

Part Number: OPA182 Other Parts Discussed in Thread: OPA387 , OPA187 , OPA186 Hello, My application requires lowest possible offset drift with + / - 5V Dual Supply. I am checking OPA182 in my design but I see the common mode voltage range is (V–) – 0.1…
Hi Naga,
As Mike implies, you need to provide us some design and accuracy requirements. I do not know what performance specification you are looking for.
As an example, here is a circuit. It is not perfect, but it may be close enough in terms of accuracy…
