Product Summary
The ADC0804LCN is a CMOS 8-bit successive approximation A/D converter that uses a differential potentiometric ladder—similar to the 256R products. The converter is designed to allow operation with the NSC800 and INS8080A derivative control bus with TRI-STATE output latches directly driving the data bus. The A/D appears like memory locations or I/O ports to the microprocessor and no interfacing logic is needed.
Parametrics
