3 Description
The ADC0801, ADC0802, ADC0803, ADC0804, and ADC0805 devices are CMOS 8-bit successive approximation converters (ADC) 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 t...
