I am using AD8421 As a differential Amplifier along with AD210 as shown below configuration.
AD210 VISS provides +/-15V at +/-5mA current as per datasheet.
AD8421 Consumes +/-2.3mA as per Datasheet.
But when I Connect in the above configuration,…
The 32-bit ADC is going to be used for DC voltage measurement.
Input voltage to diff.amp:+/-5mVdc (AD8253, AD8421)+/-50mVdc (AD8253, AD8421)+/-500mVdc (AD8253, AD8421)+/-5Vdc (AD8253, AD8421)+/-10Vd (AD8253)
I have been looking at the AD8421 and AD8253…
I plan to use AD8421 instrument amplifier for a new design ( 3kOhm pressure Wheatstone bridge) . I was considering AD8421-EP ( TRMZ), but after a short comparaison, it seems that AD8421-EP offer a better range of temperature but AD8421 ( BRMZ) could…
My question is about part AD8421
I'm trying to perform a very simple LtSPICE simulation using the AD8421. I'm running into a weird issue that I can't figure out. The gain of the system is basically non existent. I've read that analog devices cannot confirm the accuracy of their…
I have tested two AD8421ARZ with gain 991 (Rg=10). Power Supply +/-5V. Both inputs connected to gnd through 2k.
One amplifier has offset 21mV, the other has 5mV. Is this difference between amplifiers normal?
I have rigged up a circuit with AD8421,supply voltages +30V (+Vs) and -2.5V (-Vs). The circuit is working properly at only unity gain, when i have tried to put up some gain around 10 to 100, the output of the amplifier is not up to the calculated…
