ADC08031CIWM [Texas Instruments]

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. 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.
