Other Parts Discussed in Thread: INA111 Hello,
I am trying to use TINA to simulate noise behavior of the INA111 (differential mode and common mode), but I can't figure out how to do it? Is it possible?
I need to see the noise rejection performance. I …
Hi Art,
Please take a look at the following thread from Marek. I think that the best current sensing solution from 1nA to 1mA is using TIA for the application.
It may be possible to use 100Ω shunt resistor to sense the current range with instrumentation…

I have a quirky academic device to design,
I will be be passing 0-150V at 1nA to 1mA through a piece of organic tissue.
I need to measure…
Nicholas, I believe INA110, INA111, INA116, and INA128 have sufficient bandwidth in gain of 10 for your application while INA103, INA217, INA826 may have the required speed but may not be best suited for bridge application because of their relatively…
Hi Cam,
Upon reviewing the Capacitec probe and pre-amp specifications it does appear that any alternate input amplifier needs to have low-noise and very high input impedance. Even though the INA103 has very low noise, its input bias current is high (microamps…
Other Parts Discussed in Thread: INA111 I am trying to use the TPL0102 digital potentiometer as the Rg input to the INA111 instrumentation amplifier to control its gain. The INA111 works well on its own with an external resistor but does not work with…
Hello,
The INA111 and INA121 are 36V JFET instrumentation amplifiers that may be of interest. Both have TINA-TI models available.
I do not know if the ADI model can be ported into TINA-TI.
Hello Alexander,
The INA110, 111, 116, and 121 are the only FET-input amplifiers in our portfolio. Of these devices, the INA110 has the greatest slew rate (17 V/us typical) and BW (2.5MHz, G=1V/V). However, the gain of the INA110 is set by shorting…
Part Number: INA128 Other Parts Discussed in Thread: INA148 , INA149 , INA111
Hello. I need build a current sensor for a Full bridge inverter output. The nominal output voltage of the inverter is 127 Vrms. At their output there will gonna be a LC filter. …
Other Parts Discussed in Thread: INA111 , THS3202 , THS4271 Hello,
I have been using INA111 for the following circuit (3-omega measurement set-up) and it works perfectly fine up to 100KHz. However I need to push the fundamental frequency up to a few MHz…
