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.

Theserialoutputisconfiguredtointerfacewithstandardshiftregistersormicroprocessors. Detailedinformation

on interfacing to most popular microprocessors is readily available from the factory.

The ADC0832 multiplexer is software configured for single-ended or differential inputs. The differential 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 operation of the ADC0831 and ADC0832 devices is very similar to the more complex ADC0834 and

ADC0838 devices. Ratiometric conversion can be attained by setting the REF input equal to the maximum

analog input signal value, which gives the highest possible conversion resolution. Typically, REF is set equal

to V

(done internally on the ADC0832). For more detail on the operation of the ADC0831 and ADC0832

devices, refer to the ADC0834/A DC0838 data sheet.

The ADC0831AC, ADC0831BC, ADC0832AC, and ADC0832BC are characterized for operation from 0°C

to 70°C. The ADC0831AI, ADC0831BI, ADC0832AI, and ADC0832BI are characterized for operation from

–40°C to 85°C.
