Update: 30 September, 2023
The ADC08231, ADC08234 and ADC08238 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 MICROWIRETM serial data exchange standard for easy interface to the COPSTM family of controllers, and can easily interface with standard shift registers or microprocessors. Designed for high-speed, low-power applications, the devices are capable of a fast 2 ms conversion when used with a 4 MHz clock. All three devices provide a 2.5V band-gap derived reference with guaranteed performance over temperature. 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.
