- ADC0804
- In above circuit, any address 0xxx xxxx xxxx xxxx will address to the ADC.
- Procedure of using ADC
- "Write" to ADC to start a conversion. The conversion may take several hundred uS.
- Wait "INTR" from ADC, which indicates the finish of conversion.
- "Read" from ADC to read the converted data.

- ADC0820
- Procedure of using ADC0820
- Set /CS and /RD to low to start a conversion. The conversion only take 2.5 uS.
- Wait RDY from ADC0820, which indicates the finish of conversion.
- Read DB0~DB7 from ADC0820.
- Set /RD and /CS to high to end a cycle.
