Hello Itamar,
Itamar Shamay said: 1.I didn't get the same noise graph (I used your simulation in TINA)
How did you run the noise simulation? I ran this as input referred noise and changed the axis to log.

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…
Hi Hiroyuki,
Moreover, until the -5V started up, about 1V was observed at the +IN terminal.
If 1V is observed on the +IN pin before the power supply is ramped, I believe you are violating the abs max ratings of the device. See that the abs max for the…

The customer would like to use AD8421, competitor device at current sensor application based on CT.
I want to replace this device to Our INA849. Please refer…
Part Number: INA849 Other Parts Discussed in Thread: INA848 Hello,
I have a current source driving a laser diode. I would like to measure the AC component of the drive current so that I can characterize the source's noise.
I plan to use the INA849…
Hi Steve,
Since the instrumentation amplifier is configured with a high gain of 2000V/V in this application, the noise of the instrumentation amplifier input stage will dominate and define the noise performance of the circuit. The noise performance of…
Part Number: INA849 Other Parts Discussed in Thread: INA848 , , INAEVM-ALT-SO8 I have selected an INA848 IC instrumentation amplifier for a project for the following unique features observed in it’s datasheet that matches my requirement. - Output…
Part Number: INA849 Hi,
I would like to ask you about voltage noise.
According to the datasheet specification, the voltage noise changes with input stage gain.
(Fig 7-24, page 11)
I do not understand why the noise changes...
Will you tell me the reason…
Part Number: INA849 Hi TI,
I want to measure the 'current noise' of amplifier, but I don't know which method I can use to do this.
By the way, which kind measurement instrument I can choose?
I want to get the noise figure like the above figure…
