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 MICROWIRE™ serial data exchange standard for easy interface 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 derived reference. For devices offering guaranteed voltage reference 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-differential modes. In addition, input voltage spans as small as 1V can be accommodated.
