how to design a circuit framework and implement a circuit that can capture vairous signals

Now I need to design an analog conditioning acquisition circuit.
This circuit can collect various front-end analog signals and achieve switching by controlling analog switches, including voltage, current, PT100, IEPE, bridge sensors, full bridge strain, half bridge strain, and 1/4 bridge strain,
All these signals have a frequency of 25 MHz
The voltage signal can be single ended and differential, ± 10V, ± 5V, ± 1V, ± 500mV, ± 100mV, ± 50mV, ± 10mV (automatic range function)
The current signal is 20mA, 200mA
Can you tell me how to design a circuit framework and implement a circuit that can capture all signals.
Which chip did you choose to complete the design? "I have no idea what parameters should be considered in this design.".,
