可以接光电二极管，偏置电压是内部给的。

不过跨阻放大器，我们更推荐LTC6560/1或者LTC6563，他们具有更高的跨阻增益，LTC6563带宽可以得到500Mhz.

Hi Mohi,

I don't see anything obvious, but to be honest I did not spend an inordinate amount of time reviewing your ADA4350 TIA design feeding into the ADC :-).

I also wanted to point out a TIA device Preliminary datasheet for LTC6563 with ADC driver…

Hi denis.maccorin_4000_sfr.fr, 

For your TIA needs: LTC6563 (quad) is a TIA with integrated ADC driver built-in. A single version of this device is also in the works.

Let me know if you have any questions.

Regards,

Hooman
