... TYPICAL APPLICATION CIRCUIT A typical application of the ADC is shown in is provided in this example by the National Semiconductor LP2950 low-dropout voltage regulator, available in a variety of fixed and adjustable output voltages. The power supply pin is bypassed with a capacitor network located close to the ADC. Because the reference for the ADC is the supply volt- age, any noise on the supply will degrade device noise per- 5 ...
