Features • NSC MICROWIRE compatible-direct interface to COPS family processors • Easy interface to all microprocessors, or operates "stand-alone" • Operates ratiometrically or with 5 VDC voltage reference • No zero or full-scale adjust required • 2-, 4- or 8-channel multiplexer options with address logic • Shunt regulator allows operation with high voltage supplies • 0V to 5V input range with single 5V power supply • Remote operation with serial digital data link • TTL/MOS input/output compatible • 0.3" standard width, 8-, 14- or 20-pin DIP package • 20 Pin Molded Chip Carrier Package (ADC0838 only) • Surface-Mount Package Description The ADC0831 series are 8-bit successive approximation A/D converters with a 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 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. The differential analog voltage input allows increasing the common-mode rejection and offsetting the analog zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution. Key Specification Resolution 8 Bits Total Unadjusted Error ±½ LSB and ±1 LSB Single Supply 5 VDC Low Power 15 mW Conversion Time 32 µs

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
