ADC0831CCN (8 bit A/D Convertor with Multiplexer)
BD 4.500
The ADC0831 series are 8-bit successive approximation A/D converters with a serial I/O and configurable input multiplexers with 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 processors, and can interface with standard shift registers or µPs. The 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. Operates ratiometrically or with 5 VDC voltage reference No zero or full-scale adjust required or 8-channel multiplexer options with address logic Shunt regulator allows operation with high voltage supplies 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, or 20-pin DIP package 20 Pin Molded Chip Carrier Package (ADC0838 only) Surface-Mount Package
