Part Number: OPA330 Other Parts Discussed in Thread: LM7705 , , OPA388 , OPA369 , TINA-TI
I am having trouble with an active attenuator I designed as part of a piece of internal test gear.
I have a question open on stackexchange here with some additional…
Hello Hari,
Thanks for reaching out on the forum. So you can get the gain by setting the inputs to the LTC2063 amplifier to Vx. Thereupon, the upper node where Isense crosses Rsense has the voltage Vsense+Vx. If you divide the difference between this…
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…
Hi David,
If a bandwidth limit at 300kHz is not sufficient to remove the ripple, then consider using the OPA320 devise. These are the next generation products in the zero-crossover distortion line of products (OPA364, OPA365, OPA369, OPA320/322) which…
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…

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…
Hi Lucas,
Lucas Hölbling said: Is a load resistor to GND on the output required?
This technique is discussed in the datasheet of OPA364. See figure 24.
In the datasheet of OPA320 the use of a Schottky diode to generate a negative supply voltage…
Hi Alex, If your bus-voltage is 5V-USB: for generating the negative voltage rails to your current requirements you could use either the charge pump TPS6040x family, or the DC-DC Inverter TPS63700. In addition to get a very clean DC supply I would recommend…
