TIA with ADC output

I looking for a 2 stage TransImpedance TIA  with ADC integrated chip.

I've 5 Photodiodes BPW34 in parallel, 70pf x5 = 350 pF input capacitance.

I need BPW = 10Khz with very low noise and high SNR, because working with very low photodiode signal (1uA pic).

Supply voltage is:  5VDC or 3.3VDC 

Finally I need an ADC output,  with mini 8 bit resolution or more.

Thanks for help and to design an easiest and smaller circuitery chip.

    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…
