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 MICROWIRE™ serial data exchange standard for easy interface to the COPS™ family of controllers, and can easily interface with standard shift registers or microprocessors. A track/hold function allows the analog voltage at the positive input to vary during the actual A/D conversion. In addition, input voltage spans as small as 1V can be accommodated. n Test systems n Embedded diagnostics FEATURES
