Hi Tan,
ADC noise is not included and need to be added using above formula - INL, DNL, Eg and Eo are all DC parameters and do not include the ADC noise.
Having said that, as discussed in https://training.ti.com/ti-precision-labs-adcs-statistics-behind…
Part Number: INA823 Other Parts Discussed in Thread: INA283 , TINA-TI Hi, I need to use this circuit INA823 for nA current measurement, could I be recommended values for R1/R2/R3 for 0-1250nA measurement with 1nA-10nA accuracy if possible?
I would like…
Part Number: ADS8689 Other Parts Discussed in Thread: INA823 , Hi, team!
I want to calculate ADC823+ Amp8689 error.
offset voltage error :
INA823: G=1, V(OS_RTI)=V_OSI+V_OSO∕G=(20+140∕1)uV=160.06uV V(OS_INA)=G*V(OS_RTI)=160.06uV
ADS8689: V(OS_ADC)=Eo=…
Part Number: INA823 Other Parts Discussed in Thread: INA849 I got following output from INA823DR for different input. Attached circuit in the attachment.
10mV in = 1.2V 20mV in = 2.4V 30mV in = 3.6V 40mV in = 3.8V
The expected output for 40mV in is 4…

Firstly i admit i may have missed something in the data sheet but.....
supply voltage 3.3
input common mode voltage = 1v
Vref =0v
Rg=20K => Av=6
differential signal ramp from 0 --> 0.4v
Problem…
Part Number: INA823 Other Parts Discussed in Thread: OPA4187 Hi Team,
Can you estimate how much current INA823, REF50xx for amplifying a force sensor signal and 2 low pass filter OPAmps (OPA4187) need in total? Is 100mA from an LDO enough?
Thank you…
Hi Jan,
In addition to Clemens suggestion, you may also try INA823 as shown in the image below.
Jan Croes said: has a bandwidth over of 4kHz
If this is the hard requirements at gain of 1000 V/V, then you may have to pick higher BW instrumentation amplifier…
Allen,
The difference of 20nV/rt-Hz vs 21V/rt-Hz is insignificant taking into account that the normal noise process variation may be as high as 20%.
As far as the output swing goes, the only difference between INA823 and INA826 is 150mV to negative rail…
Part Number: INA149 Other Parts Discussed in Thread: TINA-TI , INA148 , INA823 , INA121 I am using IN149AMDREP to measure the voltage drop across a resistor that will typically have 2.00v across it The circuit was originally designed using IN148UA but supply…
