ADC0831 Analog-to-Digital Converter - (AD293)

Description:

These devices are 8-bit successive approximation analog-to-digital converters. The ADC0831A and ADC0831B have single input channels; the ADC0832A and ADC0832B have multiplexed twin input channels. The serial output is configured to interface with standard shift registers or microprocessors. Detailed information regarding interfacing with popular microprocessors is available from the factory. The ADC0832 multiplexer is software configured for either differential or single-ended inputs. The differential analog voltage input allows for common-mode rejection or the offsetting of the analog zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding of any smaller analog voltage span to the full 8-bit resolution. The operation of the ADC0831 and ADC0832 devices is very similar to the more complex ADC0834 and ADC0838 devices. Ratiometric conversion can be achieved by setting the REF input equal to the maximum value of the analog input signal, giving the highest possible conversion resolution. Typically, REF is set equal to VCC (internally realized on the ADC0832). For additional details on the operation of the ADC0831 and ADC0832 devices, refer to the ADC0834/A DC0838 data sheet.
