Other Parts Discussed in Thread: LMH32401, , ADS8881, ADS8860, REF6045, REF6033, REF6041, REF6030, REF6025
My design consists in detecting a light by a photodiode which I will place at the input of the LMH32401 device. At the output of the differential LMH32401 I will connect a differential ADC with SPI interface. Note that the ADC must be differential and also equivalent to a 100 Ohms load because according to his datasheet the LMH32401 is designed to drive at 100 Ohms load. Thank you for advising me an ADC who respect these conditions.
I chose ADS8861 but I am not sure that they are compatible directly, ie if I can connect them directly, knowing that the LMH 32401 is made to drive a load 100 Ohms. What do you think?
If you find that these two devices (LMH32401 and ADS8861) are incompatible, please advise me a differential TIA and a differential ADC with which I can realize my design. Note that I prefer to use differential devices to minimize common mode noise.
