Product Summary

The ADC0838CCWM is an 8-bit successive approximation A/D converter with a serial I/O and configurable input multiplexers with up to 8 channels. The ADC0838CCWM is configured to comply with the NSC MICROWIRE. serial data exchange standard for easy interface to the COPS. family of processors, and can interface with standard shift registers or μPs. The 2-, 4- or 8-channel multiplexers are software configured for single-ended or differential inputs as well as channel assignment.
