1. Introduction
`Chapter 3` experiment is about the ADC, Analog-to-Digital Converters. According to the direction, I`ll investigate the characteristics and operating principle of Successive Approximation ADCs and ADCs.
2. Equipments and components
- Capacitor: 150pF x 1
- Resister: 10㏀ x 1
- ADC0804 x 1
3. Theory
An analog-to-digital converter (abbreviated ADC, A/D or A to D) is an electronic integrated circuit, which converts continuous signals to discrete digital numbers. The reverse operation is performed by a digital-to-analog converter (DAC).
The successive approximation Analog to digital converter circuit typically consists of four chief subcircuits:
A sample and hold circuit to acquire the input voltage (Vin).
