Part number : ADC0804, ADC0804LCN, ADC0804LCD
Function : 8-Bit, Microprocessor- Compatible, A/D Converter
Package information : DIP 20 Pin type
Manufacturer : Intersil Corporation ( http://www.intersil.com/ )
The ADC080X, ADC0804 family are CMOS 8-Bit, successive-approximation A/D converters which use a modified potentiometric ladder and are designed to operate with the 8080A control bus via three-state outputs. These converters appear to the processor as memory locations or I/O ports, and hence no interfacing logic is required. The differential analog voltage input has good common- mode-rejection and permits offsetting the analog zero-input-voltage value. In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution.
1. 80C48 and 80C80/85 Bus Compatible – No Interfacing Logic Required

3. Easy Interface to Most Microprocessors
4. Will Operate in a “Stand Alone” Mode
5. Differential Analog Voltage Inputs
6. Works with Bandgap Voltage References
7. TTL Compatible Inputs and Outputs
8. On-Chip Clock Generator
9. 0V to 5V Analog Voltage Input Range (Single + 5V Supply)
10. No Zero-Adjust Required
