Part Number: INA849 Tool/software: Hi,
What is minimum active load impedance for INA849 instrumentation amplifier (i.e. what is minimum Rload)?
The electrical parameters in the data sheet presented for Rload=10 kohm. Is it typical value? Can I use Rload…
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…
Bharath,
Bharath Raj said: 1.Why all the signal are relative to high rail and not GND what is the advantage on this approach?
To avoid the need to reject common mode voltage. Signal can be as low as 1mV, common mode can be as high as 5500mV.

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…
