Part Number: INA849 Tool/software: Hello TI expert,
the simulation model of INA849 with TINA TI for 1Meg is ~75 dB with Gain = 1:
The datasheet shows a graph of CMRR vs frequency as follows:
What value could be considered as more realistic?
Thanks…
Part Number: INA849 Other Parts Discussed in Thread: TINA-TI , Tool/software: Hello,
I'm interested by the INA849 instrumentation amplifier at a gain of 5~10 but its BW is a little bit too low. I tried a simulation on TINA-TI and LTspice and the simulation…
Part Number: INA849 Other Parts Discussed in Thread: OPA445 Tool/software: Hello TI,
I am running a simulation of piezo disc connected to INA849 amplifier through JFE140, ideally I would like to modify this design with voltage generation as a piezo…
Part Number: INA849 Tool/software: Hello,
I'm looking for a way to do derivation of the noise with the INA849. How can I do to have the opamp noise (current and voltage) of the op amps inside the INA in order to take in account the gain resistor noise…
Part Number: INA849 Other Parts Discussed in Thread: TINA-TI Tool/software: Hello, I am trying to determine an accurate value for the 0.1Hz-10Hz current noise on INA849. On Page6 of its datasheet this is quoted at 100pApp. However, in Figure 7-28 it looks…
Part Number: INA849 Tool/software: hi
i need support for the above part
the requirement is we need to measure transient current of 10A/us
Is it possible to measure this transient current with this INA?
Load transient testing with high slew rates
as per…
Hey Henrik,
Henrik Rosenø said: 3. And are there specific resistor and potentiometer technologies that give less noise and distortion?
When you design using a potentiometer it is a good idea to use AC coupling especially when designing with bipolar input…
Part Number: INA849 Other Parts Discussed in Thread: TINA-TI Hi ALL
I used INA849 for the input circuit of the IR sensor. It looks like a normal differential amplifier. However, it becomes somewhat unstable at startup. Initially, IN- was connected directly…
