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
serial I/O is configured to comply with the NSC MICROW-
IRE
™
serial data exchange standardfor easy interface to the
COPS
™
family of controllers, and can easily interface with
standard shift registers or microprocessors.
TheADC08034 andADC08038 provide a 2.6V band-gap de-
rived reference. For devices offering guaranteed voltage ref-
erence performance over temperature see ADC08131,
ADC08134 and ADC08138.
Atrack/hold function allows the analogvoltage 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-differential modes. In addition, input voltage spans
as small as 1V can be accommodated.
