ADC0819 8-Bit Serial I/O A/D Converter with 19-Channel Multiplexer OBSOLETE September 26, 2009 8-Bit Serial I/O A/D Converter with 19-Channel Multiplexer General Description 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 sampled data parator. This allows the input signal to vary during the conversion cycle. Separate serial I/O and conversion clock inputs are provided to facilitate the interface to various microprocessors. Features -...
