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-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.
