ADC0801/ADC0802/ADC0803/ADC0804/ADC0805 8-Bit µP patible A/D Converters November 1999 ADC0801/ADC0802/ADC0803/ADC0804/ADC0805 8-Bit µP patible A/D Converters General Description The ADC0801, ADC0802, ADC0803, ADC0804 and ADC0805 are CMOS 8-bit successive approximation A/D converters 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...
