ADC0801LCN 8-bit A/D Converter – Datasheet

2,583 views

The ADC0801 is 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.
