I O A D Converters with Analog Multiplexer
and Track Hold Function
General Description
The ADC1031 ADC1034 and ADC1038 are 10-bit succes-
sive approximation A D converters with serial I O The seri-
al input for the ADC1034 and ADC1038 controls a single-
ended analog multiplexer that selects one of 4 input chan-
nels (ADC1034) or one of 8 input channels (ADC1038) The
ADC1034 and ADC1038 serial output data can be config-
ured into a left- or right-justified format
An input track hold is implemented by a capacitive refer-
ence ladder and sampled-data comparator This allows the
analog input to vary during the A D conversion cycle
Separate serial I O and conversion clock inputs are provid-
ed to facilitate the interface to various microprocessors
