THS4531A: Difference between THS4531 and THS4531A

Part Number:THS4531A

Hello,

I am contemplating on using THS4531A to build a Fully Differential Transimpedance Amplifier.

I realised that there is another component THS4531 which is quite similar to THS4531A.

I figured out the two components are different in following respect:

1. Harmonic Distortion@1kHz

2.Input referred offset voltage and drift

3. Input referred offset current and drift

Apart from these, are there any other differences in the two components ?

Is there any restriction on using THS4531 instead of THS4531A ?

Is there any document telling the difference between THS4531 and THS4531A ?

regards,

Ashish
