Part Number: ADS4145

I'm working on a cerebral oxygen monitor device, which has high power pulsed laser diode passing through the tissue and bone to the venous blood in the superior sagittal sinus and a high speed digitizer receives the acoustic signals resulting from the pulse light.
I'm now focusing on the acoustic signal sensor design. I've some reference parts such as AD797, ADA4930-1 and AD9255 from ADI to design the sensor pre-amp and data acquisition. I want to use TI parts in my design. Do you have any recommendations?
Also, below is the expected input signal that I need to gain up and process
Amplitude - 113uVpp
Freq range- 38kHz to 15MHz

Need ADC with 12-bit minimum, 80MSPS

Thanks

    Nhi,

    We can offer the following LVDS devices:

    Speed (Msps)            bits              Part #                 # of Converters

    125                              12               ADS4125                   1

    125                              14               ADS4145                   1

    80                                12               ADC3223                   2

    80                                14               ADC3243                   2

    125                              12               ADC3224                   2

    125                              14               ADC3244                   2

    If you prefer JESD204B parts we can recommend these as well.

    Regards,
