These converters are designed to allow operation with the NSC800 and INS8080A derivative control bus with Tri-state output latches directly driving the data bus.
These ADCs appear like memory locations or I/O ports to the microprocessor and no interfacing logic is needed.
Differential analog voltage inputs allow increasing the common-mode rejection and 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.
