I need to sample voltage at a very high rate (say for like 10000 Hz) and with a very good precision(at least 10-12 bit ADC will do). So I am in need of an Analog-to-Digital Converter(ADC) which has a very high sampling rate (sampling rate has to be constant and known), can be interfaced with Arduino Mega or Raspberry Pi and noise should be neligible to minimum level of voltage magnitude that it can count. Can anyone suggests me with any ADC that follows these characteristics?

10Ksps and 12bit-resolution adcs are fairly common for onboard ADC. you should be able to find lots of mcus that have adc modules that can do that.
even for an external adc, that's not difficult at all. because of the speed, you are likely looking at a spi adc module.
precision is another matter.
