ADC0832 Analog-to-Digital Converter - (AD289)

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 the most popular microprocessors is available from the factory. The ADC0832 multiplexer is software configured for differential or single-ended inputs. Differential analog voltage input allows for common-mode rejection or offsetting the analog zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding of any smaller analog voltage range 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 analog input signal value, which yields the highest possible conversion resolution. Typically, REF is set equal to VCC (internally accomplished on the ADC0832). For further details on the operation of the ADC0831 and ADC0832 devices, refer to the ADC0834/A DC0838 datasheet.
