Need amplifier like OP497 but smaller size

We have had success in building an amplification circuit with the OP497 G class amplifier. Our application is amplifying a very low current DC input signal from a photodiode which will be charge integrated after the output in a CAEN V792N QDC card.


We are looking for something a little smaller in size to fit on our amp boards. We still need low input bias current and a quad op-amp package with 14 pins. Do you have an amplifier like the OP497, or a smaller version of the OP497? The approximate dimensions are 4mm x 8mm (package only, without pins). For reference, we need something the same size as the LT1817S amplifier:

(See page 19 for dimensions on "S-package").


Thanks!

    Hi Kole,

    Do you already have a board fabricated? Can your board accommodate something slightly wider? I believe the AD8624 will perform very closely to the OP497. The size of the IC is 4.4mmx5mm, please see Figure 62 on the datasheet. If you require a package with the exact dimensions of 4mmx8mm though, I can recommend something else.

    Thanks,

    Kris
