8-Bit, Microprocessor-Compatible, A/D
Converters
The ADC080X 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.
