ADC1031/ADC1034/ADC1038 10-Bit Serial
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.
