Hi Lin,
The ADA4051-2 has very low offset voltage and would probably be a better choice than the AD8502.
Since the bandwidth of your signal is only 20Hz, the gain-bandwidth of the ADA4051-2 is high enough.
Best Regards,

刚刚又买了ADA4528-2和ADA4051-2再试试。
Before I used the kind of attachment methodI have bought a 1000 ada4051-2
But input voltage error.
Hello.
ADUC7060 for 4-20mA loop processing, taking into account the internal PGA power is too large, and the maximum PGA gain is 64, the rest is a digital gain. Can you provide the ADC low power mode PGA consumption power? Modeled on the CN0216_00_1024…
Hi,
This is a duplicate thread. Please refer to : Worse case power dissipation (Pd) & Thermal resistance θjc (Junction to Case) Regards,Goz
I do this，is ok? (ADA4051-2 Composition Differential amplifier use VCC :5V )
I only know a little English。
I hope you can understand。
ADUC7060 Differential signal amplify:
Consider the power consumption, can not be used within the PGA amplification, use an attachment circuit(OP: ADA4051-2 ), can I?
That the circuit where you need to modify？(Signal change 1~2 mV/V)
Signal processing…
Hello,
The some datasheet that it have describe the input resistance, like ADA4051, but the others datasheet didn't describe the input resistance, like AD8539 and AD8500
How to know input resistance? especially no describe the input resistance???

Hi everyone!
I'm new here so bare with me!
I'm looking for an op-amp with similar features/specs to the ADA4051, but in a PDIP packaging (throughhole/breadboard size). I have attached the data-sheet for the ADA4051, but my basic requirements…
