ADC08031/ADC08032/ADC08034/ADC08038
8-Bit High-Speed Serial I/O A/D Converters with Multiplexer
Options, Voltage Reference, and Track/Hold Function
General Description
The ADC08031/ADC08032/ADC08034/ADC08038 are 8-bit
successive approximation A/D converters with serial I/O and
configurable input multiplexers with up to 8 channels. The se-
rial I/O is configured to comply with the NSC MI-
CROWIRE ™ serial data exchange standard for easy inter-
face to the COPS ™ family of controllers, and can easily
interface with standard shift registers or microprocessors.
The ADC08034 and ADC08038 provide a 2.6V band-gap de-
rived reference. For devices offering guaranteed voltage ref-
erence performance over temperature see ADC08131,
ADC08134 and ADC08138.
A track/hold function allows the analog voltage at the positive
input to vary during the actual A/D conversion.
The analog inputs can be configured to operate in various
combinations of single-ended, differential, or pseudo-differ-
ential modes. In addition, input voltage spans as small as 1V
can be accommodated.
