What's the consequence of leaving the exposed pad unconnected on the ADA4084-2? The datasheet says it must be connected. Will the result be poor thermal performance or are there other potential issues
The ADA4084-2 is expected to be a little lower in price than the OP284. Final prices will be set when the product is released in a few weeks. Please check back with us, or at our website http://www.analog.com/en/precision-op-amps/precision-rail…
Anne sent me the two links. For the LPF, use the ADA4084-2.
For the BPF, use the ADA4851-2.
I am trying to design a ADA4084-2 into my latest design, but I am receiving strange results when I do noise modeling using the Spice circuit. The voltage noise at the output is extremely large, even with relatively small feedback resistor values. It almost…
ADA4084-2, but you only need RR I/O for buffers. How are you using them?
I removed the OP284's and replaced them with the ADA4084-2's.
No oscillation now.
You can use ADA4096-2 or ADA4096-4. These parts have typical input bias current of ±3nA, typical input offset voltage of 35uV, can be powered with 30V single supply or ±15V dual supply, and have rail-to-rail input and output.
You can also…
I probably posted a message in the wrong forum. Please find below the question related to ADA4084
Datasheet Table 3 specifies that at +/-5V, typical input impedance is [100KOhms||1.1pF]Differential and [200MOhms||2.5pF]Common mode.
Thanks for your reply,
But ADA4084-2 required dual supply(+Ve and -Ve).But my case only single supply.
Also what about AD8223 instrumental amplifier.
