DESCRIPTION
The ADC08131/ADC08134/ADC08138 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 MICROWIRE serial data exchange standard for easy interface to the COPS™ family of controllers, and can easily interface with standard shift registers or microprocessors. All three devices provide a 2.5V band-gap derived reference with ensured performance over temperature. A track/hold function allows the analog voltage at the positive input to vary during the actual A/D conversion.
