Overview
ADC0802, ADC0803 ADC0804 August 1997 8-Bit, MicroprocessorCompatible, A/D Converters Description The ADC0802 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 commonmode-rejection and permits offsetting the analog zero-inputvoltage 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.
Features • 80C48 and 80C80/85 Bus Compatible - No Interfacing Logic Required • Conversion Time < 100µs • Easy Interface to Most Microprocessors • Will Operate in a “Stand Alone” Mode • Differential Analog Voltage Inputs • Works with Bandgap Voltage References • TTL Compatible Inputs and Outputs • On-Chip Clock Gener...
