Other Parts Discussed in Thread: LPV811 , OPA369 , INA190 , LPV821 , TINA-TI , LPV812 Hi,
Please find the attached current sensing circuit.
It's output voltage equation is given by VOUT =( RLOAD *RSENSE* I SENSE)/RIN.
As per my knowledge the equation is…
Thanks a lot for your time! This is really useful. This is the kind of support that makes us choose your products over the rest.
You're right in design factors, however Low Power is order of magnitude more important than space. But I do need accuracy…
Other Parts Discussed in Thread: OPA2369 , OPA369 , TLV3401 Hi
I am using below circuit to detect the motion of human body. I have tried to simulate the same in Pspice but not getting output. Also i wanted to give 0-5v (Differnet Values) plus on R3 or in…
Other Parts Discussed in Thread: OPA2365 , OPA2350 , OPA365-EP , OPA365 , TINA-TI , OPA320 , OPA369 , OPA364 , OPA350 Hi,
I have a TIA design that uses a OPA2365. The schematic is shown below.
The TIA function performs well over the bandwidth of interest, 1-500kHz…
Other Parts Discussed in Thread: LMP91000 , OPA369 Hello, I'm considering your Potentiostat AFE LMP91000 for my low power gas sensing circuit wich I intend to develop as a part of my master's thesis.
I however strumbled over the noise characteristic…
Mike,
There is no OPA769 so I think you are referring to OPA369. Is that correct?
Be aware that the electret capsule you have used requires a maximum of 500uA current to operate. Seems like you are working with nano-power amplifiers when the real significant…
Other Parts Discussed in Thread: OPA378 , OPA347 , OPA369 , OPA334 , OPA313 , OPA376 , OPA330 , OPA333 , OPA188 , OPA180 , OPA170 , OPA171 Narional Semiconductor developed a method of measuring the EMI rejection ratio (EMIRR) of OpAmps in AN-1698. (This application…
Hi,
We are trying to build an front end solution for an implantable medical application (monitoring EEG signals).100uV - 10mV.
The integrated solutions like ADS1298 , ADS1198 etc are good options for this but their power consumption is way too much than…
Attached active filter presentation should help answer your questions. In general, if you run an AC Analysis you can look at the slope of the closed loop transfer function , Vout/Vin. If it is 20dB/decade it is first order and if it is 40dB/decade it…
Opa211 and OPA209 are very good low noise amplifiers that are commonly used for active filter applications. Also, the attached presentaiton covers some active filter design considerations. Note that Gain Bandwidth is a key consideration for active filters…
