National Semiconductor ADC0834

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.

GENERAL DESCRIPTION

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. n Operates ratiometrically or with 5 VDC voltage reference n No zero or full-scale adjust required n 2-, 4- or 8-channel multiplexer options with address logic n Shunt regulator allows operation with high voltage supplies n 0V to 5V input range with single 5V power supply n Remote operation with serial digital data link n TTL/MOS input/output compatible n 0.3" standard width, 8-, 14- or 20-pin DIP package n 20 Pin Molded Chip Carrier Package (ADC0838 only) n Surface-Mount Package Key Specifications n n n n n Resolution Total Unadjusted Error Single Supply Low Power Conversion Time 8 Bits
