ADA4857 as charge amplifier

We were using AD8620 Op Amp in our previous application but now want to use the ADA4857 op amp as integrator / charge amplifier. I have compared the following parameters of both the op amps




Sl. No. Parameters AD8620 ADA4857
1 Supply voltage +/-5V +/-5V
2 Noise (In nV/Sqrt(Hz)) 6 4.4
3 Gain-Bandwidth product (In MHz) 25 110
4 Power supply current / amplifier
(In mA)
3.5 5.5
5 Output Current
(In mA)
+/-30 50
6 Rail to Rail Out No No
7 Amplifier per package 2 2
8 Temperature Grade Ind Ind
9 Temperature (deg C) –40°C to +125°C –40°C to +125°C
10 Package SOIC LFCSP
11 Price ($) 15.35 6.13
12 Height (In mm) 1.75 1
13 Length (In mm) 6.2 4
14 Breadth (In mm) 5 3.75

Should I go ahead with the ADA4857 in our application as charge amplifier?

Do I have to compare any other parameters?

What should be the selection criteria as a charge amplifier/integrator?

Regards
