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!

  • Kris,

    Thanks for the reply! The specs on the AD8624 look like they will work great. However, we do have a board fabricated so unfortunately we need an IC a little closer to the exact dimensions.

    The dimensions given on the link I shared above are (8.560-8.738)mm length, (3.810-3.998)mm width and (5.791-6.197)mm width with pins. Additionally, the spacing is 1.270mm between each pin. Something closer to this would be great.
