ADC0819 Datasheet (National Semiconductor) - 8-Bit Serial I/O A/D Converter

ADC0819, 8-Bit Serial I/O A/D Converter

The ADC0819 is an 8-Bit successive approximation A/D converter with simultaneous serial I/O.

The serial input controls an analog multiplexer which selects from 19 input channels or an internal half scale test voltage.

An input sample-and-hold is implemented by a capacitive reference ladder and sampl
