Part Number: INA849 Other Parts Discussed in Thread: AM6442 , OPA388 , OPA328 , OPA810 Dear team,
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 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…
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 Other Parts Discussed in Thread: TMUX6219
Dear, TI support Team.
We would like to use INA849 to build a programmable gain circuit with a minimum 10up-p, maximum output amplitude 10Vp-p, bandwidth from 500Khz to 1MHz, and gain…
Hi Liu,
not sure whether I understand you correctly, but operating the INA849 with floating ground may be dangerous for the INA849. You risk a damage. See the built-in protection diodes of INA849 (only one drawn). If the INA849's ground float too much…
