ADC 0811

⁍The ADC0811 is an 8-Bit successive approximation A/D converter with simultaneous serial I/O. The serial input controls an analogue multiplexer which selects from 11 input channels or an internal half scale test voltage. An input sample-and-hold is implemented by a capacitive reference ladder and sampled data comparator. 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.
