Yes, the required precision from the electronics is extremely high. I wasn't that much interested in the physics other than semiconductors before, but with the new job I began learning much more about the physics side of the things and it is very enjoyable. However, you don't need to know that much physics for designing the interface electronics as long as you know what you want to measure in terms of electrical parameters (like capacitance, inductance, charge, etc.) and you know the transfer functions of the system to be measured.
