The ADC0834 (4-channel) and ADC0838  
(8-channel) multiplexer is software configured  
forsingle-ended or differential inputs as well as  
pseudo-differential input assignments. The differ-  
ential analog voltage input allows for common-  
mode rejection or offset of 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.  
The ADC0834AC, ADC0834BC, ADC0838AC, and ADC0838BC are characterized for operation from 0°C to  
70°C. The ADC0834AI, ADC0834BI, ADC0838AI, and ADC0838BI are characterized for operation from 40°C  
to 85°C.
