Its a bit of a general question.
www.ti.com
www.analog.com
www.linear.com
all have parametric search facilities on their websites. 

I use the LTC2440 24 bit ADC quite a bit. It is easy to set up and has an SPI
interface. It is 4.5 volt + but there are slower chips in the LTC24XX range that
work on 2.7 volts + .
