The ADC0804 8-Bit Converter is a CMOS 8-bit successive approximation A/D converter that use a differential potentiometric ladder—similar to the 256R products. 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 A/Ds 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.
