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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
