Most CMOS ADCs found in microcontrollers and ASICs have a sampled data comparator input structure. When the ADC charges
the sampling cap, it requires instantaneous charge from the output of the analog source such as the LM57 temperature sensor
and many op amps. This requirement is easily accommodated by the addition of a capacitor (C
). The size of C
depends

on the size of the sampling capacitor and the sampling frequency. Since not all ADCs have identical input stages, the charge
requirements will vary. This general ADC application is shown as an example only.
