ADS4145: Part Search

Nhi Hua
Prodigy 120 points
Part Number: ADS4145
Other Parts Discussed in Thread: ADS4125, , ADC3223, ADC3243, ADC3224, ADC3244
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
